Sisters of Death (1977)
In the initiation of a girl into a secret society, she is killed in a game of russian roulette. Years later her sorority sisters are invited to a mansion for a party, but don’t know who is their host. This is definitely drive-in fare from 1977. Probably the one that showed at midnight. But, it’s almost fair. That’s more than you could say of most movies of the same genre.
