For Guest Cast, see The Programme Guide by Jean-Marc Lofficier.
Synopsis: In the very far future, the Tardis lands on Frontios, last
refuge of a group of Earth survivors, led by Plantagenet. The colonists
are under seige by mysterious meteorite storms. Also, an unseen force is
kidnapping humans in Frontios' underground. The Doctor eventually discovers
that the colony is secretly controlled by the Tractators, large worm-like
aliens with gravity-controlling powers, who have been using the missing colonists
as living batteries. Their leader, the Gravis, plans to turn Frontios itself
into a giant hollow spaceship in which they can roam throughout the Universe.
But the Gravis' desire for the Tardis enables the Doctor to cut him off
from the other Tractators, and thus render him, and the other Tractators
helpless. As the Tardis leaves, it is caught up in a time corridor...
Shown 26 January 1984 to 3 February 1984.
