Open (1970)

Sinopsis

Jayson and Andy, a young gay couple, have been together for 2 ½ years. Their love story seems like a fairy tale, until Jayson suggests opening up the relationship. Andy, internally bewildered and upset, reluctantly agrees to please his partner. As the hook ups, jealousy, and secrets progress, demonic manifestations of the "others" invited into their lives begin to haunt and torment them both, especially a susceptible Andy. As the old saying goes "Be careful who/what you invite into your home".
