  A series of stills from The Caves of Androzani.

The Doctor and Peri arrive on the second of the twin world of Androzani Major and Androzani Minor. Minor does not seem to have much on offer - lots of sand and some caves. Or blowholes, as the Doctor explains, for the molten mud which spews up whenever the two worlds move close to one another. Investigating the caves the two travellers come into contact with a ball of some sticky, stinging substance. Further along they come across a weapons dump - which turns out to be a supply left by a group of gun runners. A small group of soldiers arrive and arrest the Doctor and Peri. Accused of gun running they are sentenced to death by firing squad.

The real gun runners take out another patrol of soldiers and then get rid of the weapons. Now they must meet up with Sharaz Jek, a scientist hiding in the caves, and also the man controlling the supply of Spectrox. Spectrox is a wonderful boon, in a refined form it extends life, in its raw form (a sticking, stinging substance) it is higly dangerous - anyone touching it will be dead with 48 hours...

The Doctor and Peri must elude the military, the gun runners and Sharaz Jek and hope that they can find a cure to Spectrox Toxemia (caused by coming into contact with raw Spectrox), but time is running out.
