Scientific investigator Alan Brooks (Forrest Tucker) is called to the isolated Alpine village of Trollenberg after a mountain-climber is gruesomely decapitated. On his journey, he meets mind-reading sisters Anne and Sarah Pilgrim (Jennifer Jayne) who accompany him to the village. Brooks soon uncovers a sinister radioactive cloud beneath the summit at his friend Professor Crevett's (Warren Mitchell) observatory. Unravel the horrifying alien secret hidden within the poisonous fog and discover why Anne's powers pose a threat to it in this chilling tale.
