STORY PLOTLINE
On holiday in Lanzarote, a young American girl named Peri narrowly escapes drowning when she is rescued from the sea by Turlough and taken into the TARDIS to recover. The Doctor is on the island because the TARDIS has detected a mysterious signal being transmitted from an unknown artifact.
The Master reasserts his control over Kamelion and gets it to bring the TARDIS, along with the Doctor, Turlough and Peri, to the planet Sarn, where he is hoping to use that world's supply of revitalising numismaton gas to restore his body - accidentally shrunken in an experiment with his tissue compression eliminator weapon - to its correct size.
