I Burn All Over (1979)4.2 /10

Storyline:  Susan Hemingway hooks up with a guy at a discotheque, has unwilling sex (Brigitte Lahaie joins in on the action) and is drugged and sold off to a "deluxe bordello" where a bunch of dirty, moaning girls are kept in a constant state of excitement by some sort of sex-gas that is pumped into their living quarters.
