It's Chritsmas, 1963, when six-year-old Gerald starts playing a new
game: 'Daleks'.
It's a game full of dangers and daring and terrible, mutated montsers.
Gerald's parents think it's harmless at first.
But then things start getting out of hand, as Gerald inists there are
yetis in the basement, and Cybermen invading London.
Desperate for help, what Gerald's family really need, right now, is a
Doctor.
