A real shocker! When a pretty student at an exclusive High School [sic] disappears mysteriously, a terrible chain of events begins... with one gruesome murder following another. As the death toll mounts it becomes obvious that a mentally unbalanced student holds the key. Everything will be revealed at a macabre birthday party where the guests have one thing in common... they are all corpses! Horror and terror on a grand scale with Glenn Ford leading the cast list and director J. Lee Thompson executing shocks at non-stop pace.
