STORY PLOTLINE
The TARDIS visits the planet Deva Loka, where Nyssa remains behind in the ship to recover from a mild mental disorientation while the Doctor, Tegan and Adric explore. Tegan falls asleep under some wind chimes and becomes possessed by an evil force, a Mara.
Also on Deva Loka is a survey team assessing the planet for colonisation, but three of their number have disappeared and the remainder - Sanders, his deputy Hindle and the scientist Todd - are encountering difficulties in their dealings with the outwardly primitive but telepathically gifted native people, the Kinda.
