SWINGER’S MASSACRE aka INSIDE AMY (1975, 105 min, Joyanne Mitchell, Marsha Jordan, Rene Bond, Uschi Digard), is a grim, serious and epic hard-R-rated film filled with sex and murder. A husband and wife become active in the ’70s swinger scene only for the husband to become murderously jealous. Look for X actresses like Uschi, Rene Bond and Marsha Jordan in bit roles.
