The Chaperone(1974)

Extremely rare roughie in the vein of LAST HOUSE ON THE LEFT. A group of young hippies go camping accompanied by an uptight, sexually repressed, middle-aged chaperone. The chaperone is envious of the youngster's liberated ways and doesn't trust one of the young men. Then the group is plagued by a series of vicious knife murders. Directed by Israeli-born Jourdan Alexander (as "Jaacov Jaavoci") and written by Svetlana, both of whom would make a name for themselves in hardcore porn, this one's nearly impossible to track down nowadays. The only known home video release occurred in Australia on the King of Video / Video Budget label and their release is reduced down to just 70 minutes from the original 87.
