Death Warmed Up

As a child, Michael Tucker (Michael Hurst) is used as a test subject for mind control drugs developed by evil scientist Dr. Howell (Gary Day (actor)), which cause him to unwittingly kill his parents. After spending seven years in a mental institution for the murders, Tucker, his girlfriend Sandy (Margaret Umbers) and his two friends Jeannie (Norelle Scott) and Lucas (William Upjohn) set out on a trip to a remote island on which Dr. Howell's clinic is located. Desperate for revenge, Tucker is determined to infiltrate the scientist's base and kill him with no mercy. After tracking him down, he kills Howell's mob of mind controlled slaves, but in the resulting mayhem both Jeannie and Lucas are killed. At last Tucker proceeds to brutally kill Howell after repeatedly stabbing him in the stomach with a knife. After escaping the clinic, Tucker (who appears to have gone insane from all that has happened) and his girlfriend return to their holiday home, however they discover it has unexpectedly caught fire. Tucker who steps out to investigate is struck by a falling electrical line and is electrocuted to death, leaving Sandy alone weeping as she's overcome with grief.
