“Help me, Doctor,” the voice called into the night; into all corners of space and time.

With the first Eight Doctors locked away in the confines of the Time Lock, the Ninth, Tenth and Eleventh Doctors converge, crossing their own timelines to help a small, frightened girl.

With her memory lacking, little Serenity had no ideas into her past or where she came from. The only thing that the Time Lords know is that she’s immensely powerful; so powerful that her pleas found three different Doctors in three spots along his own timeline.

But who is this girl? A lonely ten year old from the Cotswolds or is she something more? Can they help her, or is this merely an elaborate trap for the Last of the Time Lords?
With the Ninth, Tenth and Eleventh Doctors together, you can be sure anything can happen!

With Christopher Eccleston, David Tennant and Matt Smith as the Doctor.
