6.07. The Anachronauts
An experimental timeship smashes into the TARDIS, and the crews of both ships wake up on a desert island. Has the TARDIS been destroyed? And why doesn’t the Doctor want to escape?
Then, Steven and Sara find themselves on the wrong side of the Berlin Wall in 1966. And their only way back to the TARDIS is to betray the Doctor.
