The Doctor is on trial for his life. Plucked out of time and space by the Time Lords, he is charged with transgressing the First Law of Time. He must defend himself against the prosecution led by the sinister Valeyard...

The trial begins as the Time Lords review an adventure from the Doctor's recent past. The setting is Ravolox, where the Doctor and Peri find themselves caught in the conflict between a warrior tribe, a pair of intergalactic con-men and a god-like robot. But deep below the surface of the mysterious planet lie secrets that threaten the very fabric of the universe. And to protect them, drastic measures have been taken that will shock the Doctor to his very core...
