Two-time Academy Award-winner Olivia de Havilland stars in a suspenseful shocker that also features future Oscar nominee James Caan in his first major film role. Alone in her residence over a sweltering holiday weekend, a widow (de Havilland) is accidentally trapped in her home elevator during a power failure. Her meticulous, well-organized world is shattered as the elevator, stalled nine feet above the floor, becomes a claustrophobic torture chamber - a cage. Unable to escape, her situation becomes desperate when the emergency alarm attracts a swarm of terrifying intruders - a drunken derelict (Jeff Corey) and his boozy prostitute friend (Ann Sothern), as well as a trio of young delinquents (Caan, Rafael Campos, Jennifer Billingsley) who embark on an orgy of wanton vandalism and sadistic brutality that culminates in murder.
During a power failure, a wealthy widow becomes trapped in an elevator in her mansion, and is subsequently terrorized by all manner of intruders drawn by her cries for help.
An invalid woman, trapped in her private home elevator, becomes the victim of a thieves and three sadistic hoodlums.
