The Trollenberg Terror.

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

A United Nations investigator crosses paths with a pair of psychic sisters on his way to Trollenberg observatory in the Swiss Alps, which has been plagued by a series of mountaineer disappearances that may be related to a radioactive cloud at the mountain's south face.
