Bihagin: Bilibid Boys (1981)

The movie portrays seven wayward men who suffer within the walls of the national penitentiary. They serve their sentences as if they are living their regular free, luxurious lives outside the cold bars of the prison, in open air, able to go where they want when they want. Four of the men--Nandong (Al Tantay), Noel (Mark Gil), Butch (Gabby Concepcion), and Caloy (Choy Acuña)--are gay men who feel attracted to Steve Guanzon (Alfie Anido) and eventually sodomize and rape him.
