After witnessing a gangland killing, Piper Laurie takes refuge at Montana's Glacier National Park, but she soon learns the gang is hot on her trail. But who could it be? Victor Mature or Vincent Price? This taut thriller, complete with great touches from the master of disaster (producer Irwin Allen) ends in a nail-biting climax among the treacherous mountain crevasses of the National Park.

Vinnie is the consumate villain here - an amoral, slimy rat. And we love him for it!
