A woman arrives at a remote mansion to link up with her former lover who has a fear of being buried alive. They get married despite the opposition of his sister but his paranoia gets worse and impacts all their relationships. As always with a Roger Corman film this has a different twist to the horror genre. The plot has some unusual twists and some good production scenes. The performances from Ray Milland and Hazel Court are fine, but the strength of the film lies in the script.
