As you may know, Doctor Who: The Light at the End stars former TV Doctors Tom Baker, Peter Davison, Colin Baker, Sylvester McCoy and Paul McGann. The story itself features the first eight incarnations of everyone's favourite Time Lord. It also features that infamous Time Lord, the Master, played by Geoffrey Beevers.

November 23rd 1963 proves to be a significant day in the lives of all eight Doctors…

It's the day that Bob Dovie's life is ripped apart…

It's also a day that sets in motion a catastrophic chain of events which forces the first eight incarnations of the Doctor to fight for their very existence. As a mysterious, insidious chaos unfolds within the TARDIS, the barriers of time break apart…

From suburban England through war-torn alien landscapes and into a deadly, artificial dimension, all these Doctors and their companions must struggle against the power of an unfathomable, alien technology.

From the very beginning, it is clear that the Master is somehow involved. By the end, for the Doctors, there may only be darkness.
