The Crawling Eye

In this 1958 British science fiction horror film, a United Nations investigator teams up with a pair of psychic sisters to investigate mysterious accidents at a Swiss mountain resort, where a radioactive cloud may be hiding an alien life-form that's causing decapitations and other bizarre occurrences. As they delve deeper, they discover a trail of clues pointing to a similar incident in the Andes Mountains three years earlier. With the help of the sisters' psychic powers, the investigator must navigate a treacherous mountain rescue operation and face off against an otherworldly creature that's wreaking havoc on the resort.
