The Doctor and Rory begin their quest to find Amy who has been kidnapped. She's also given birth and they have her baby girl, Melodie, as well. They begin by scouring the universe where the Doctor calls in debts and head for Demon's Run where Amy is being held. The only one who refuses to join him is River Song. The battle is short-lived and both Amy and Melodie are saved. Perhaps the battle to save them was too easy. It's clearly Melodie the kidnappers were interested in and her DNA reveals she's something more than just human. They've also been fooled however and the baby has been taken. When River Song appears, she reveals who she truly is.
Amy has been kidnapped by Madame Kovarian and taken to Demon's Run for her newborn baby, Melody, that appears to be the ultimate stratagem for war apparently. Meanwhile The Doctor and Rory are recruiting everyone they might need to free Amy and Melody, everyone except River Song who is not willing to go until the end because this will be the day when The Doctor founds out who she is...
A member of The Doctor's team has been abducted and he will call in every favor and maybe even go to war to get them back.
- Amy now has a baby, but she and Melody are held captive in the season finale by panto-style villainess Madame Kovarian (Frances Barber) and the Doctor is raising an army to rescue her as the drama continues. But as he and Rory race across galaxies, calling in long-held debts and solemnly given promises, his enemies are laying a carefully concealed trap.
In her cell in Stormcage, River Song sadly acknowledges that the time has come at last today will mark the Battle of Demons Run and the Doctors darkest hour. Both sides will make their sacrifices and River Song must finally reveal her most closely guarded secret to the Doctor. Theres the return of some familiar monsters, including a Sontaran, Cybermen and Silurians, who assist the Doctor and Rory in their attempt to rescue Amy and Melody.
