On 6 December 2011, a prequel to the episode was released online. The Eleventh Doctor is seen on a spaceship holding a red button which, when he lets go, will cause the space ship to explode. While holding the button, he has phoned the TARDIS to speak to Amy asking her to rescue him, although he does not have his co-ordinates, Amy cannot fly the TARDIS, and she is not on the TARDIS. The Doctor wishes Amy a Merry Christmas before letting go of the button, and the spaceship explodes.

Amy reminds the Doctor he needs to have an adventure once in a while, the Doctor complies and sets the TARDIS to its "adventure setting". After a series of malfunctions, the ship lands in the middle of the London 2012 Olympic Games, where they are visited by a panicked Olympic runner, who claims he is being chased. His pursuer is revealed as a Weeping Angel, who is seeking to seize the Olympic Flame and rob the planet of the good will and spirit it symbolises. The Doctor vanquishes the Angel with the sonic screwdriver, and the runner resumes his mission. Before he leaves, he gives the Doctor his gold medal. As the Doctor prepares to embark on another adventure with Amy, the Weeping Angel begins to reform.
