When the Doctor realizes that Amy has been abducted, he assembles an army of individuals from across time and space to help him and Rory recover her from an asteroid base, Demon's Run. However, River insists that she can't go with them, because Demon's Run will be the day that the Doctor reaches his highest point, and then falls to his lowest low... and learns who River really is.
