Summoning The Doctor

Amy and Rory are driving through a corn field in a car with Amy giving directions badly. After a lot of twists and turns they suddenly arrive in a clearing and stop when they see The Doctor standing by the TARDIS. He shows them a copy of the local newspaper which has a front-page story about an unusual crop circle that spells out the name ‘Doctor’ but in addition to the letters, that Amy and Rory have just spelt out in the corn field, is a line heading straight towards where they are standing. Suddenly a red sports car appears from the corn and drives up to them knocking The Doctor to the ground. A woman, about Amy's age, then steps out and points a gun at The Doctor.

This woman is in fact a ‘friend’ of Amy who she and Rory have known since they were all children. Mels is though a troublemaker and has always been in trouble but has always been supported by her best friend Amy.

With the sound of police sirens approaching Mels orders The Doctor to take the three of them in the TARDIS. But inside Mels shoots the control console causing the TARDIS to go out of control as they head for Berlin, Germany in the year 1938.

Mels

At this time in Earth’s history a strange man is watching a Nazi general. The man walks into the general's office and becomes his double. He sucks the general into him, where he is killed by anti-bots. Inside the machine are also people who are controlling the shapeshifter which now tries to kill Adolf Hitler. But the out of control TARDIS crashes through a window and knocks the shapeshifter to the floor. On exiting the TARDIS The Doctor, Amy, Rory and Mels are shocked to discover that they have just saved Adolf Hitler. The Nazi dictator, on realising that his assassin is back on his feet tries to shoot the shapeshifter.

Unfortunately he misses, shooting Mels instead. As Mels dies it is discovered that she is in fact Melody Pond, Amy’s daughter who was abducted at the Demons Run when she was a baby (see "A Good Man Goes to War"). Thinking that have only just located Amy’s long-lost daughter – at the point at which she dies – they are shocked when they witness her regenerate into the person they know as River Song. With Adolf Hitler safely locked in a wardrobe, the shapeshifter scans Melody Pond/River Song and discovers that she is the ‘weapon’ that will kill The Doctor – this is because this is what she has been ‘programmed’ to do and the reason why she was kidnapped by Madame Kovarian at Demons Run.

Adolf Hitler Is Attacked

Melody Pond/River Song tries to kill The Doctor several times, but he thwarts her. Finally she runs out of ideas and so kisses The Doctor before jumping out of a window to go shopping for clothes. But before she leaves she reveals that she has just poisoned The Doctor by kissing him with poisoned lipstick. As The Doctor starts to die, he orders Amy and Rory to catch their daughter as this is the Melody that will be if Madame Kovarian keeps her. Outside Amy and Rory witness her kill some Nazis soldiers using her regenerative energy. She then steals their guns and flees on a motorbike.

Amy and Rory follow on a second motorbike, the shapeshifter following them on a third motorbike. The Doctor meanwhile manages to get into the TARDIS. There the TARDIS voice simulator takes on the form of young Amelia Pond. After much debate, the voice simulator reveals that fish fingers and custards will control the pain, but he will still die.

Melody Pond/River Song steals all the clothes from people in a restaurant and works on her ensemble. Amy and Rory then arrive outside the restaurant, pursued by the shapeshifter. Inside the restaurant Amy approaches Melody Pond/River Song who is trying on different outfits. But this is not Amy but the shapeshifter. The shapeshifter is about to kill Melody Pond/River Song when The Doctor arrives, in the TARDIS, wearing evening clothes.

Amy, The Doctor and Rory

Meanwhile Amy and Rory awake inside the shapeshifter, where anti-bots attempt to kill them, but they are saved by one of the crew. They discover that the shapeshifter is called the Teselecta and is being used to track down wanted criminals – hence why the attempted assassination of Adolf Hitler and its interest in River Song. The Teselecta prepares to kill Melody Pond/River Song, but The Doctor begs it to stop resulting in Melody Pond/River Song becoming frozen in place. The Doctor asks the Teselecta for information on himself and Amy persuades them to give The Doctor what he wants. The Teselecta though starts to torture Melody Pond/River Song, until Amy turns off all of their security clearance devices. This causes the anti-bots to start tracking them all down. To escape death the crew teleports away leaving just Amy and Rory being hunted down inside the Teselecta.

Free once more Melody Pond/River Song is persuaded by the dying Doctor to help her parents. Amy and Rory are about to be killed when the TARDIS materializes around them. Thinking that it is The Doctor who has come to save them they discover that Melody Pond/River Song has flown the TARDIS, after it taught her how. The trio then return to The Doctor but he says there is no way for him to survive.

With just seconds of his life left he passes on a message to Melody Pond/River Song. When Amy quizzes her as to what The Doctor said Melody Pond/River Song asks her who River Song is. To answer her, so that there is no doubt, Amy instructs the Teselecta to change its form to that of River Song. Melody Pond therefore sees herself and this prompts her, after confirming with Amy and Rory that The Doctor is a worthy person, to save The Doctor. To do so though she sacrifices her remaining regenerations to revive him, almost killing herself.

After leaving Berlin, The Doctor, Amy and Rory take Melody Pond/River Song to the largest hospital in the universe. The Doctor claims that they must now let her find her own way. Back in the TARDIS, The Doctor has also downloaded some information about himself from the Teselecta – in particular he has now discovered the day of his death…
