The Trollenberg Terror

“The nightmare terror of the slithering eye that unleashed agonizing horror on a screaming world!”

Alan Brooks (Forrest Tucker), a United Nations investigator, is on his way to the Trollenberg observatory in the Swiss Alps when he meets the Pilgrim sisters, who are psychic. The observatory sits beside a mountain where climbers keep disappearing, and a radioactive cloud clings to the south face. Quentin Lawrence puts Sarah (Jennifer Jayne) and Anne (Janet Munro) at the center, and the sisters share a bond the mountain seems to be testing.
