When the TARDIS lands on the supposedly peaceful planet of Dido at the end of the 25th century, the Doctor, Barbara and Ian discover a crashed spaceship waiting for help. The only survivors have been murdered by natives, apart from a young orphaned girl and a paralysed man. But who is the strange creature Koquillion that they are afraid of? And will they remain safe long enough to be rescued?
