Doctor Who

The Trial of a Time Lord- The Terror of the Vervoids (3) (23x11)

Air date: Nov 15, 1986

A course change that takes the Hyperion III closer to a black hole could prove unwise when there are so many aboard ship with hidden agendas. Disappearances continue, a murderer remains at large, and one person finally crumbles under the strain of harbouring a guilty secret.
