Kick-boxing action from the Roger Corman stable. Martial arts star Don Wilson is Jack Dillon, an ex-policeman. He is hired as bodyguard to Shanna (Deirdre Imershein), an up-and-coming rock starlet, who is being hounded by John Sweet (Matthias Hues), a psychotic Vietnam veteran who kills with his bare hands. Sweet is after Shanna because she looks remarkably like his dead mother, and she has just released a version of a song his mother sang in the '60s. Sweet also had an incestuous relationship with his mother as a child, and the scars this has left make him determined to eliminate the hapless singer.
