Prom Night

In Bridgeport, the deranged high school teacher Richard Fenton is obsessed by the teenager student Donna Keppel; she witnesses him murder her family to stay with her, but Richard is arrested and sent to prison for life. Three years later, the traumatized Donna is feeling better but is still under psychological treatment and taking pills. On her prom night, she goes with her boyfriend Bobby and two couples of friends to the Pacific Grad Hotel for the party. But the psychopath Richard has escaped from prison and is lodged in the same floor in the hotel chasing Donna, stabbing her friends and staff of the hotel that cross his path.
