Plot
The Doctor and Nyssa have returned to the TARDIS to find it missing various pieces of equipment and its dimensions unstable. Thomas Brewster refuses to explain where he has been since he "borrowed" the TARDIS and what has happened to it. Drawn by a distress beacon, the TARDIS crash lands on a time reef where the interior subsequently implodes, leaving the companions stranded. They need to find their way back to normal space.

Brewster originally stole the TARDIS in The Haunting of Thomas Brewster, leaving the Doctor and Nyssa stranded in Victorian London. They regain the TARDIS in the following story, The Boy That Time Forgot.
