Christmas is a time for family, they say – which is why the Doctor has invited his grand-daughter Susan, and great-grandson Alex for Christmas dinner in his time and space machine. But who, or what, is the spectre at their yuletide feast?
Venturing deep into the dark heart of the TARDIS, Susan uncovers her past, Alex is told his future – and the Doctor finds himself caught in a deadly dangerous present!
