The last of any species is one that surely deserves to be preserved for as long as possible, especially when they are the cause of the extinction of their entire race.
The Doctor and Leela arrive on the planet Colophos, a dead, seemingly barren world which is just dust and sand. The chance to relax is offered but there is something deadly lurking in the background and the Doctor and Leela, along with the crew of the survey ship The Oligarch have to fight for their lives against an enemy who revels in being unseen.
