You Go Sisters!

SISTERS OF DEATH-1976-During a sisterhood initiation involving Russian roulette, a would be member is killed. 7 years later... someone is planning a reunion. Judy (Claudia Jennings), Sylvia (Cheri Howell), Francie (Cheryl Alberoni), Diane (Sherry Boucher), Penny (Roxanne Albee), the remaining girls reunite and are driven to a remote house by two guys Mark (Paul Carr) & Joe (Joe Tata) where someone is watching them. Only Penny had any hesitation to go. Everything seems to be provided for their entertainment. Even Mark and Joe come back although they aren't really welcome. The next day the watcher reveals himself. He is the father of the girl who died at their initiation 7 years earlier. Though the girls explain that they all loved his daughter and her death was ruled a tragic accident, he insists one of them secretly hated her and purposely set her up to be murdered and now he’s going to find out who! There's an electrified fence around the grounds and since the guys are trapped there too, they decided to help out.

Penny is the first to go, strangled to death. Dad spends much of his time in a secret room making bullets near a shrine for his dead child. He also plays the flute to an accompanying record and has a flashback. Apparently he and daughter were a musical duo. After Sylvia is menaced by a tarantula,  Diane is killed with a pair of scissors. Joe runs into the electric fence after being chased by a dog. Francie is locked in the cellar with a rattlesnake. In the end Sylvia is in league with Dad, who has a Gatling gun he plans to use in his own game of Russian roulette leading to a surprise twist ending involving Judy and Paul. The director of this low budget cat and mouse drama Joe Mazzuca, directed several episodes of TV's THE BIG VALLEY and did various production jobs on many animated cartoon series.
