Gar Seberg (Bo Svenson) and his wife Ellen Seberg (Yvette Mimieux), return to his home town, a ski resort in the Colorado Rockies. As they arrive, the town's annual Snow Carnival is spoiled by the disappearance of some vacationers. Resort owner Carrie Rill (Sylvia Sidney) fears losing business and tries to keep the disappearances a secret, while local Sheriff Paraday (Clint Walker) initially attributes the killings to a lone savage bear.
