The TARDIS deposits the Doctor, Tegan, Turlough and their android ally Kamelion aboard a prison ship. A ship with just one prisoner: Nustanu, last warlord of the Zamglitti – monstrous, mind-bending mimics able to turn themselves into mist.
A ship that's in trouble, and about to make a crash-landing...
On a planet of mists.
