The Impossible Astronaut Envelopes in the colour of the TARDIS contain a position, date and time for The Doctor, River Song, Amy and Rory to meet in Utah in 2011. They make a trip to the Oval Office in Washington, D.C., 1969. This episode will feature the Silence, referred to several times in series 5.

Numbered envelopes in the colour of the TARDIS containing a position, date and time arrive for River Song (numbered 2), Amy and Rory (numbered 3) to meet in Utah, 2011. They all travel there where they meet The Doctor, who is now eleven hundred and three years old. They then go to a nearby lake, and Amy sees a mysterious man standing on distant rocks, only to forget the moment she stops looking. An astronaut then walks out of the water; the Doctor seems to recognize the figure. He tells his companions not to interfere no matter what happens. He then grimly goes to greet the astronaut, and the astronaut shoots the Doctor twice, and then a third time while he is regenerating, killing him permanently. A man then appears and says that he also received a blue envelope numbered 4. The group then burns the Doctor's body, as per his wishes. Read More! (Caution spoilers!)

Day of the Moon In the three months since the end of "The Impossible Astronaut", the Doctor, Amy, Rory and River Song have been attempting to track the Silence, an alien race who cannot be remembered after they are encountered. Canton Delaware, under the ruse of capturing them as criminals, helps to reunite the group inside a special prison at Area 51 containing the TARDIS. Though they do not yet know the name or motive for the aliens, the Doctor's allies have discovered they exist across the entire planet, and have the ability to place post-hypnotic suggestions in humans they encounter. The Doctor plants a communication device in each of the group's hands to record audio of meetings with the Silence. As they travel to Cape Canaveral shortly before the launch of Apollo 11, Amy tells the Doctor she was mistaken and is not pregnant. Read More! (Caution spoilers!)

The Curse of the Black Spot Following a distress signal, the TARDIS and its crew lands aboard a 17th century pirate ship stranded in the middle of a calm ocean. The crew have been terrorised by a Siren-like creature (Lily Cole), who marks people with black spots on their palms after they are injured. She would then appear and lull her victims to touch her, which would apparently disintegrate them. Rory Williams (Arthur Darvill) receives a cut during a tussle with the pirates and, knowing the Siren is using water as a portal, the Doctor (Matt Smith) instructs everyone to seek refuge in the ship's dry magazine.

The Doctor's Wife In deep space, the Doctor receives a message unit, called a hypercube, that knocks on the door of his TARDIS and floats inside. This particular hypercube has a snake mark on one of its sides and contains a distress call. The snake is the mark of a Time Lord called the Corsair, who the Doctor knew particularly well. It also displays the co-ordinate where the Time Lord was last seen, beyond the edge of the universe.

Upon traveling to the location - a world which resembles a vast, night-time junkyard - the TARDIS mysteriously shuts down (apparently caused by the deletion of the TARDIS matrix). The Doctor is confident that there's enough time rift energy in the atmosphere to eventually re-power the TARDIS, so in the meantime he, Amy and Rory explore their surroundings. They're greeted by Auntie, Uncle, Nephew (an Ood with green glowing eyes) and Idris, a young woman who greets the Doctor with intense confused excitement. The Doctor repairs Nephew's inactive communication globe - upon which the voices of several Time Lords asking for help begin to echo through the air. Nephew is told to take Idris to a cage in order for her to stop ranting, as well as to stop her kissing and biting the Doctor. Auntie and Uncle then explain that the world they're standing upon is actually a sentient entity called "House", which shelters them and subsequently welcomes the three visitors with a disembodied voice.

The Rebel Flesh As the Doctor continues the unresolved TARDIS scan on his companion Amy's possible pregnancy, the TARDIS is caught in the first waves of a "solar tsunami" and materialises on Earth in the 22nd Century. The Doctor, Amy, and Amy's husband Rory (Arthur Darvill) find themselves on a remote island in the future, where a factory housed in a former castle monastry pumps a valuable, highly corrosive acid to the mainland. The skeleton crew of the factory uses a self-replicating fluid called the Flesh from which they create exact doppelgängers of themselves, colloquially called gangers. The crew controls the gangers from special control beds, operating the hazardous environment of the factory via the disposable bodies. The Doctor, initially posing as an inspector, fears the worst part of the solar tsunami will strike the solar-powered factory soon, threatening those still remaining, and offers to take the crew in his TARDIS. The foreman, Miranda Cleaves (Raquel Cassidy), refuses to shut down the factory until she receives orders from the mainland. As the solar storm begins, the Doctor races to disconnect the solar collector, but an electrical strike hits the castle, throwing the Doctor off the tower and knocking everyone else inside unconscious.

The Almost People The ganger of the Doctor struggles to reconcile his old regenerations, quoting from them, before he stabilises. Both Doctors look the same but can be told apart by their different shoes. The two Doctors determine that they need to restore power to the factory in order to send a distress call to the mainland. Amy becomes distrustful of the ganger Doctor and asks him not to call her "Pond", his sobriquet for her.

While the group escapes from the chapel, the Jennifer ganger explains that every time a ganger dies, the last question in their eyes is "Why?". She convinces the other gangers to rise up against humanity. Rory, still looking for Jennifer, eventually finds two Jennifers, each insisting they are the 'real' Jennifer. They fight each other; one finally pushes the other into an acid pool, where she melts and is revealed to be a ganger.

The humans and the Doctors arrive at the power control room. Sensing the Flesh in his head, the ganger Doctor runs outside, and Amy runs after him. She confronts him about the death she witnessed, but the ganger Doctor does not respond. He echoes the Jennifer ganger's question: "'Why?' It's all the eyes say. 'Why?'" Read More!

Let's Kill Hitler In modern-day Leadworth, Amy and Rory create a crop circle to gain the Doctor's attention. He arrives with his TARDIS, but they are soon joined by Mels, Amy and Rory's childhood friend who knows of Amy's "raggedy Doctor" and was responsible for Amy and Rory's relationship; Amy subsequently named her daughter Melody after Mels. Mels, on the run from the police, brandishes a gun and coerces them to escape in the TARDIS and "kill Hitler". Inside, she fires the gun, hitting the central console which fills the time machine with a poisonous gas and sends it out of control.

Meanwhile, in Berlin 1938, "Justice Vehicle 6019", a Teselecta robot manned by a human crew from the future miniaturised inside it and able to take on the appearance of other humans, is seeking to deliver justice on war criminals like Adolf Hitler. They do this by using the Teselecta's weapons to torture the criminal, near the end of their timeline. Having taken on the appearance of a Wehrmacht officer to meet with Hitler, they are surprised when the TARDIS crashes into Hitler's office. Hitler, already panicked, fires on the Teselecta, but his aim is poor and strikes Mels. As Rory locks Hitler in a cupboard, the TARDIS crew finds Mels regenerating, becoming the woman they know as River Song-Melody as a grown woman. River, having been trained by her captors to kill the Doctor, makes several attempts but the Doctor has taken precautions to nullify these. Instead, River kisses him and before disappearing into the streets of Berlin, reveals that her lipstick is a poison that will kill the Doctor within the hour and prevent his regeneration. The Doctor orders Amy and Rory to follow River, passing her his sonic screwdriver, while he returns to the TARDIS to try to discover a cure. The Teselecta, aware that the Doctor's death on 22 April 2011 is a "fixed point in time" ("The Impossible Astronaut"), instead follow Amy and Rory in chasing down River, having identified her as their most wanted war criminal, responsible for the Doctor's death.

Night Terrors The Doctor decides to make a "house call" after his psychic paper receives a message from George, a frightened 8-year-old child, asking his help in getting rid of the monsters in his bedroom. On arrival at a council estate on present-day Earth, the Doctor, Amy, and Rory split up to try to locate the child. The Doctor, taking the guise of a social services worker, finds the right flat, and meets George's father, Alex, while his mother Claire is working a night shift. Through Alex's photo album, the Doctor learns that George has been frightened all his life, fearing many of the sounds and people around the flat and is helped to cope by various habits, including metaphorically placing his fears within his wardrobe.

The Girl Who Waited The Doctor takes Rory and Amy to the planet Apalapucia, claiming it is a top holiday destination, but is unaware that the planet is suffering from a fatal plague, Chen7, that affects beings with two hearts and can kill them within a day. The native population has created "kindness centres", where those infected by the plague are placed in one of several thousand accelerated time streams, allowing them to live out their lives whilst in communication with their loved ones through special glass lenses in waiting rooms. On their arrival, Amy is separated from the Doctor and Rory, and becomes stuck in an accelerated time stream. As the Doctor and Rory discover Amy's location, they are approached by one of the facility's Handbots, a white faceless robot with human-like hands. The Handbot explains about the plague, and failing to recognise the Doctor or Rory as alien, attempts to administer a dose of medicine that would be fatal. The Doctor warns Amy of this, and tells her to wait, promising to rescue her. The Doctor and Rory return to the TARDIS with a glass lens, which the Doctor uses to lock the time machine onto Amy's timestream. Meanwhile, Amy discovers Interface, providing vocal control over the complex's computer systems, and learns she can mask her presence from the Handbots using the emissions from the time engines driving the accelerated time streams.

The God Complex The TARDIS, while travelling to a new planet, arrives in what appears to be a 1980's Earth hotel, but the Doctor recognizes it as an alien structure specifically designed to take that appearance. They soon meet a group of four, humans Rita, Howie, Joe, and the alien Gibbis, each who had previously been taken from their routine lives and found themselves in the hotel. The four explain that there is a Minotaur-like beast in the hotel that consumes others. It does this by enticing them to enter one of the many rooms in the hotel which contains their greatest fears, upon which they become brainwashed to "praise him" and allow themselves to be taken, their bodies left without any signs of life; many others have experienced this, and photos of them and their fears cover many of the hotel's walls. The hotel is inescapable - its doors and windows walled up - and its halls and rooms can change on a whim. The Doctor, Amy, and Rory soon find the TARDIS has also disappeared, and the Doctor warns them from opening any door they are drawn to, for fear of being possessed. Read More! (Caution spoilers!)

Closing Time The episode prologue begins showing two shop workers in a department store closing up for the evening. One of them tells the other to go home, before going to the changing rooms, as the lights flicker, to clear out stragglers. As she approaches a cubicle with someone in it the lights begin to flicker more rapidly before show opens the curtains and a Cyberman grabs her.

After the theme song plays, the main episode begins with Craig Owens' (James Corden) wife leaving the house a holiday and Craig repeatedly saying that "he does not need help". The Doctor then arrives at his house, with Craig exclaiming "she did not!" thinking that his wife (who also knows the Doctor) called him. In actual fact, the Doctor says he is just visiting, and is about to leave, when he realizes that Craig is not alone at their new house. Panicking, the Doctor whips out his sonic screwdriver and begins searching the house, before finding Alfie, Craig's baby. After talking to Craig for a while, and reassures Craig that he is only here for a social visit whilst acting suspicious and searching for something, the Doctor walks out and tries not to "notice" things.

The Wedding of River Song It's been 5:02 on 22 April for a long time and something is wrong with time. The Doctor makes a final trip to Lake Silencio in Utah. Despite River's attempt to cheat fate by draining her suit's weapons, the resulting fracture as the universe begins to collapse prompts the Doctor to force River to let the events surrounding his death play out. However, as the episode concludes, the Doctor reveals that he worked with the Teselecta ("Let's Kill Hitler") to fake his death, allowing him to return to his old low-key life as a wanderer, but he is left keenly aware that the moment will come, when the question will be asked: "Doctor Who?"
