Sisters of Death, which is included in a countless number of Mill Creek box sets, is not necessarily the greatest film ever made but it is a personal favorite of mine.
This 1977 film opens with a very baroque sorority initiation that ends with one of the sisters being killed in a game of Russian Roulette. A few years later, the surviving sisters are invited to an isolated and lavish estate where it turns out that the dead girl’s father (well-played by Arthur Franz) is looking for revenge. This film is predictable and a lot of the plot depends on people refusing to use any common sense but Sisters of Death is such a fun little melodrama that I can’t complain too much. The film plays out like a surprisingly violent Lifetime movie and it has one of those wonderfully cynical 1970s endings.
Enjoy!
