The Doctor's Meditation In a prequel, the episode entitled "The Doctor's Meditation" was released in Russia, Canada, the USA and Denmark on 15 and 16 September 2015, alongside a 3D cinematic release of "Dark Water" and "Death in Heaven". On 18 September, this was released on Facebook in the United Kingdom, and also made available through other online channels. In this prequel, the Doctor appears in medieval times alongside Bors, who appears to be a loyal friend, and in the 6 minute clip, questions who he must face, asking whether he faces an old friend or a foe. The Doctor replies that he must meditate, but has trouble doing so.

The Magician's Apprentice In an unknown time period, a war takes place on an extra-terrestrial battleground. The conflict has been going on for many years, as evidenced by a mixture of primitive and advanced technologies used in the fighting. While running across a war zone, a boy becomes trapped inside a field of 'handmines': creatures which are hands with eyes that kill by dragging the victim underground. The Doctor arrives and tries to save the boy, tossing him his sonic screwdriver so they can communicate and encouraging him to survive. However, when the Doctor asks the boy his name, he is shocked and horrified when the boy says his name is Davros, the future creator of the Daleks.

Centuries later, a creature named Colony Sarff, an agent of Davros, visits several worlds in search of the Doctor, including the headquarters of the Shadow Proclamation, an intergalactic police force, and the planet Karn. His message for the Doctor is that Davros is dying and that "Davros knows, Davros remembers". Colony Sarff reports to an ailing Davros that the Doctor cannot be located. Davros, still in possession of the Doctor's screwdriver, advises Sarff to seek the Doctor's friends, as they will be able to locate him. Read More! (Caution spoilers!)

The Witch's Familiar After being seemingly killed by the Daleks at the climax of "The Magician's Apprentice", Clara and Missy surface outside the Dalek city. Missy explains how they managed to escape: by using the energy emitted from the Daleks' weapons to teleport themselves away via their vortex manipulators (which they'd used to find the Doctor in the previous episode), destroying the devices in the process. Missy illustrates the method by relating a previous instance in which the Doctor performed the same trickery.

Meanwhile the Doctor, not believing Clara to be dead, forces Davros out of his life-support wheelchair and uses it to break into the same room where the Supreme Dalek is, safe from Dalek fire power due to the force-field generated by the wheelchair. He attempts to force the Daleks to find and return Clara to him, but the Daleks believe that she is dead. Colony Sarff, however, appears in snake form from Davros' chair and forces the Doctor into unconsciousness. Read More! (Caution spoilers!) Download the closed captions for this episode!

Under The Lake In an underwater base in the year 2119, a joint military-industrial team discover an unidentified vessel in a long-submerged town. While examining it, they uncover mysterious symbols carved onto the inside of the stark white interior. When one of the ship's engines activates, the hangar catches on fire. The group flee the room but their commanding officer, Moran, is killed. Once they have left the hangar, the group flee to a corridor, only to turn around and see Moran standing in front of them in a ghost-like form, who then attacks them alongside another apparition.

The Doctor and Clara arrive at the base days later, which now appears abandoned. They encounter the apparitions, which lead them to the ship. They examine it and discover the same markings. The apparitions then attack and chase them to a Faraday cage, where the rest of the crew have been hiding out since the ghosts cannot pass through its walls. The crew, now led by a deaf woman named Cass, relates what happened before, but have no idea what's causing any of it. The Doctor identifies the other ghost as being an alien from Tivoli ("The God Complex"), a cowardly species more likely to surrender than attack. The base then shifts back into 'day' mode, making it safe to leave the chamber; for some reason, the ghosts can only appear and operate during the 'night' mode. Read More! (Caution spoilers!)

Before the Flood The episode opens with the Doctor explaining the bootstrap paradox to the audience: a hypothetical time traveler decides to go back in time to meet Beethoven, whose music he admires. However, he discovers that Beethoven never actually existed. The time traveler then decides to publish Beethoven's music himself, essentially 'becoming' Beethoven. But, the Doctor asks, how did the music first originate, then? "Who really composed Beethoven's Fifth?"

The episode then continues from the events of "Under the Lake." The Doctor arrives with Bennett and O'Donnell at the Army base in 1980, before it was flooded, on the day the spaceship landed. They encounter the Tivolian Prentis, still alive at this point, and find that the writing has not yet been carved into the wall. Prentis reveals that the spaceship is actually a hearse carrying a deceased conqueror called The Fisher King. Back in the future at the underwater base, Clara, Cass and Lunn realise that the Doctor's ghost is uttering a list of their names instead of coordinates. When the Doctor contacts Clara and is informed about his ghost, he is badly shaken by this certain knowledge of his future. Clara forcefully encourages him to try to change events, but the Doctor argues that he cannot and ultimately accepts the eventuality that he must die to keep events in motion. He tries to get information from his ghost, but instead it unlocks the Faraday cage, releasing the other ghosts. Back in 1980, the Fisher King is revealed to be alive, writing the words on the ship's wall, killing Prentis, and dragging the stasis chamber away before hunting down the Doctor's group. Read More!

The Girl Who Died Under attack from a battle fleet, the Doctor rescues Clara from asphyxiation in space by materialising the TARDIS around her. He lands the TARDIS on Earth, and they are captured by Vikings. The Doctor tries to frighten them by brandishing his sonic sunglasses, but an unimpressed Viking simply breaks them. The Doctor attempts to use his "magic" to impress the Vikings into letting them go. He claims to be Odin, but they dismiss him as an impostor. Suddenly, an image of Odin appears in the sky, commending the Viking warriors' bravery and inviting them to Valhalla. A squad of armoured suits arrive, using weapons that appear to disintegrate the warriors. The Doctor deduces they are using advanced imaging to target the warriors and teleport them away; Clara tells Ashildr, a young woman from the village, to use part of the sonic sunglasses to free them, but the two women are struck by the weapons after the sonic technology was scanned. The armoured suits disappear, leaving the Doctor alone with the non-warriors of the village.

Clara, Ashildr, and the other Vikings find themselves aboard a spacecraft. The male Vikings are killed by being drained of their adrenaline and testosterone, but Clara and Ashildr escape. They meet "Odin" who is actually the leader of the Mire, a species that prides itself on its merciless reputation. Clara attempts to negotiate peace, but Ashildr, enraged by what she has seen, declares war for her people. "Odin" states he will launch an attack in 24 hours and returns Clara and Ashildr to the surface, to the relief of the Doctor. Clara brings the Doctor up to date, and the Doctor encourages the remaining villagers to abandon the village until the Mire have left. They refuse, willing to make a stand despite their lack of battle skills. The Doctor attempts to train them to fight, but they are far too weak and incompetent to stand up to the Mire. The Doctor tries to devise another plan. He discovers that Ashildr is a storyteller who uses homemade articulated puppets. Able to understand "Baby", he translates for the blacksmith's baby, who is crying about the "fire in the water". The Doctor realises that this refers to the electric eels that the fishermen have caught, and this becomes the basis of his plan to save the villagers. Read More! (Caution spoilers!)

The Woman Who Lived Alone and on the trail of an alien artefact, the Doctor interrupts a highwayman known as "the Knightmare" carrying out a highway robbery in 1651 England. The Doctor finds the artefact in the coach's luggage but the vehicles drives off before he can take it. Talking to the robber, he finds that 'he' is in fact Ashildr, the Viking girl made immortal in the previous episode. Over her years of everlasting life, she has lost many of her memories, and has isolated herself in order to avoid the pain of losing loved ones. The Doctor learns that she has renamed herself "Me" due to her loneliness. She begs the Doctor to take her away from this world, but he refuses. Flicking through her journal, the Doctor finds memories ripped out and pages burdened with tear marks. He also discovers that Me previously had three children, all of whom she lost to the Black Death.

Me and the Doctor steal the artefact from a house, flee by climbing out of the chimney and escape an ambush by a rival highwayman, Sam Swift. The Doctor calls the artefact 'the Eyes of Hades' and he theorises that it is linked to ancient Greek mythology as a way of opening a portal to the afterlife or into space. The next morning, the Doctor finds out that by day, Me is "Lady Me" and lives as a wealthy woman with a servant. He then meets Me's ally Leandro, a leonine alien stranded on Earth who was the artefact's original owner. In return for Me tricking the Doctor into helping him, Leandro has agreed to let her come with him to travel the galaxy. However, in order for the portal to be activated, the artefact requires another person's death. Me ties up the Doctor and states her intent to kill her old blind servant Clayton for this end, but the Doctor opposes it. Two pikemen arrive to announce that "the Knightmare" is reported to be in the area and Sam Swift is about to be hung at Tyburn. Me hands the Doctor over to them and sets off to use Swift's death instead of Clayton's to activate the artefact. Read More! (Caution spoilers!) Download the closed captions for this episode!

The Zygon Inversion Bonnie, the leader of a small splinter group of shapeshifting Zygons that intend to start a war with the humans they live among, has taken Clara's form, keeping her body in a Zygon pod. Clara finds herself in a dream-based version of her flat, able to control Bonnie's actions to a small degree due to a telepathic connection between them. Clara is able to thwart Bonnie's first attempt to shoot down the Doctor's plane. Though the second rocket strikes and destroys the plane, the delay has given the Doctor enough time to escape safely with Osgood. Later, Bonnie finds a peaceful Zygon disguised as a human, and causes his body to revert to its Zygon nature in front of a shopping mall south of London. She uses Clara's cell phone to record and upload the footage. Meanwhile, Clara, through the telepathic connection, uses Bonnie to text the Doctor that she is awake without Bonnie's knowing it. Bonnie goes to UNIT's headquarters to try to find information on the Osgood Box, but learns that the Doctor has given that information to Clara. In interrogating Clara via their telepathic connection, Bonnie learns the Osgood Box is in the Black Archives under the Tower of London.

The Doctor calls Bonnie and from tics she exhibits, recognises that Clara is able to give him small clues through Bonnie as to her pod's location. The Doctor and Osgood converge on the mall, the same one where Bonnie's footage was taken, finding it empty save for the lone Zygon Bonnie revealed. Fearing that he might have started a war due to revealing himself, he opts to kill himself instead of being discovered. As the Doctor and Osgood prepare to look for Clara, they are met by the Zygon that has disguised itself as Kate Stewart, and two guards, who capture him and take him to join Bonnie. As they near the Black Archives, Kate reveals that she is not a Zygon, having shot and killed the one that cornered her in Truth or Consequences, New Mexico and falsified the report of her death to Bonnie. She kills their Zygon guards, and the Doctor expresses his frustration at her violent methods. Read More! (Caution spoilers!) Download the closed captions for this episode! Right click and 'save as'

"Sleep No More The episode opens as Gagan Rassmussen, the lead researcher on the Le Verrier Space Station in orbit around Neptune sometime in the 38th century, addresses a camera to record a message, warning the viewer not to watch this but explaining how the video, assembled from various recordings made over the last few hours, will help put together events leading to this point. Rassmussen continues to narrate through the episode as events are played out.

A rescue ship from Triton arrive at the station in response to a sudden absence of communications with the station, with four soldiers: Nagata, Chopra, Deep-Ando, and 474, a cloned grunt. They find the station empty with no signs of its crew, when they encounter the Doctor and Clara. They encounter creatures made of sand (later called Sandmen by Clara) that chase them; Deep-Ando is separated from the others as they take shelter. As the others try to contact Deep-Ando, Clara inadvertently is dragged into a Morpheus sleep pod before the Doctor frees her: Morpheus claims to compress a whole month worth of sleep into a five minute period, allowing people to work around the clock. They find Morpheus' inventor, Rassmussen, hiding in another pod, who explains that it works by sending out an electronic signal to the brain, changing it to enable this process. The Doctor fears this has had a side effect, that the Sandmen creatures are made up of the dust that collects in the eye, and now, after consuming the host and other crew on the station, are after them. They find that the song associated with Morpheus, "Mr. Sandman", lures the creatures to them. Meanwhile, Deep-Ando is killed while trying to escape a Sandman. Read More! (Caution spoilers!)

Face the Raven Rigsy contacts Clara through the TARDIS' phone, asking for her and the Doctor's help. They arrive at Rigsy's flat in London, finding he has settled down with a wife and newborn daughter. He has no idea of the origin of a tattoo on the back of his neck that is counting down towards zero, and lacks any memories of the previous day's events; his mobile phone is also cracked and data from the previous day wiped. The Doctor scans him with the TARDIS, discovering he had contact with aliens in the last day, and is due to die when the countdown reaches zero. Though the Doctor feels there's nothing he can do, Clara insists that he try. Assuming the presence of aliens hiding in London, the three look for a trap street where they might be hiding. They eventually come across it, aided by a flood of memories that Rigsy recalls once the TARDIS is able to restore the data on his mobile.

Within, they find themselves among several aliens, using a misdirection system to both hide the street from the average humans, and to make themselves appear human to each other. The aliens are led by Me (who the Doctor and Clara previously knew as the now-immortal Ashildr), who acts as mayor among the group. Me explains the aliens here are refugees, and that Rigsy had been sentenced to death for killing Anah, a two-face Janus female; he was injected with Retcon to forget what happened, and then given the time to say goodbye to his loved ones; the tattoo is a Chronolock that leads a Quantum Shade, appearing normally as a Raven, to its bearer anywhere they might flee to kill them when the mark reaches zero. The Doctor and Clara believe that Rigsy had been set up for murder, and Me allows them to investigate the case, but tells them they have to convince those that live on the street of Rigsy's innocence to keep the tense truce between the various alien species that live there.

Heaven Sent Following the events of "Face the Raven", the Doctor is teleported into a glass chamber located in a structure resembling a large castle. Upon investigating the surrounding corridors, he finds a series of screens scattered around the castle. The screens relay the vision of the Veil, a cloaked creature which is slowly and constantly stalking the Doctor around the building. The Doctor quickly concludes the castle and the Veil are designed to frighten him for some purpose. The Veil chases the Doctor to a dead end. Admitting that he sees no way to escape death, the Doctor confesses that he is afraid to die, leading the creature to stop. The entire castle structure rotates and reconfigures in response, opening an exit at the end of the corridor that the Doctor was trapped in, beyond which is a bedroom with an ancient, faded portrait of Clara Oswald. The Veil follows the Doctor into the room, forcing him to leap out the window to escape. During his leap, the Doctor has an inner monologue, determining how he will survive the fall by imagining himself aboard the TARDIS answering questions from a silent Clara. The Doctor lands in an ocean surrounding the castle, finding that the seabed is littered with thousands of skulls.

The Doctor returns to the castle, finding a room with a fireplace where exact copies of his clothes are drying. He swaps his wet clothes for the dried copies, leaving his old clothes drying in the same fashion as the copies he found. Entering a courtyard of the castle, the Doctor finds a fresh grave and a spade, concluding that he is meant to dig the grave up. While digging, the castle's local sun sets and the Doctor notices that the constellations do not match any location within the range of the teleporter that brought him to the castle. After digging deep enough, the Doctor finds a stone with the message "I am in 12". The Veil then reappears and corners the Doctor once again within the grave. The Doctor experiences another inner monologue within the TARDIS, where he remembers his earlier escape where the Veil stopped after he told the truth and realises that the creature is designed to extract confessions from him. The Doctor admits that he originally left Gallifrey because he was afraid rather than bored. The Veil once again stops, allowing the Doctor to escape. Read More! (Caution spoilers!)

Hell Bent In Nevada, the Doctor enters a diner and encounters a waitress physically identical to Clara. He begins to tell her a "story" about Clara; neither appears to recognize the other. The episode then flashes back to Gallifrey, where Time Lord President Rassilon attempts to have the Doctor imprisoned and then executed. The Time Lord military instead pledges its loyalty to the Doctor, who is seen as a war hero. After exiling Rassilon and the High Council, the General and Ohila press the Doctor for details about "the Hybrid" destined to conquer Gallifrey and stand in its ruins; in response, the Doctor tells them he will need help.

The Doctor has the Time Lords use an "extraction chamber" to retrieve Clara from her timeline just before the instant of her death, leaving her alive while between two beats of her heart, thus pulseless and unable to age. The General attempts to explain the situation to Clara, but the Doctor steals his sidearm and, after confirming that he can still regenerate, kills him to cover his and Clara's escape. The pair flee to the Cloisters, the stone computer that serves as a repository of the knowledge of dead Time Lords. Upon her recovery, the General and Ohila give chase and attempt to convince Clara to come with them and for the Doctor to tell them what he knows. Clara turns the tables, distracting them long enough for the Doctor to steal a TARDIS from the workshop below the Cloister, just as he did so long ago. Read More! (Caution spoilers!)

2015 Christmas Special - The Husbands of River Song On Christmas Day 5343 on the human colony of Mendorax Dellora, the Doctor is mistaken by a servant, Nardole, for a surgeon hired by River Song to attend to her dying husband, King Hydroflax. River, who has not yet met the Doctor's present incarnation, fails to recognise him and increasingly frustrates him with her flirtations with Hydroflax. River takes the Doctor aside to discuss the operation he is supposed to be performing; the Halassi Androvar, the most valuable diamond in the universe, has become lodged in Hydroflax's brain during a raid on the Halassi vaults and is slowly killing him. River wants "the surgeon" to remove his entire head, considering it quicker and easier.

They are interrupted by Hydroflax who has listened to their conversation. He detaches his head from his mechanical body and orders it to kill them. While River defends herself the Doctor grabs Hydroflax's head and threatens to put him in the garbage disposal, creating a stalemate and allowing Ramone, River's actual husband, to teleport her, the Doctor and Hydroflax's head outside of the ship. Believing Nardole to have information about River, Hydroflax's body decapitates him to use his head as its own.

Although the Doctor is convinced that River knows who he is, she denies it. She reveals she purposely crashed Hydroflax's ship in their location knowing the Doctor would be in the area with a TARDIS. Being unfamiliar with his new set of regenerations she has an incomplete set of his faces and Ramone has only been able to find the TARDIS, not its owner; River decides they will just have to borrow it instead. However the TARDIS's safeguards prevent it from taking off when it detects that Hydroflax's head and body are respectively inside and outside the TARDIS.

Hearing Nardole calling for help, Ramone is tricked and uploaded into Hydroflax's body as well. Hydroflax's head allows his body to locate the TARDIS, and using Ramone forces its way inside. With Hydroflax's head and body now both in the TARDIS it is able to travel to the starship Harmony and Redemption, where River requests that the Maître d', Flemming, deadlock seal the baggage hold in order to prevent Hydroflax's body from pursuing them further.
