Rent Society (1989)

Teenager Bill Whitney (Billy Warlock) has always felt like the odd one out in his wealthy, upper-class Beverly Hills family. For some reason, he just doesn't seem to fit in. But his sense of alienation takes a sinister turn when he hears an audio recording of his sister's coming-out party, which seems to implicate his family and others in a bizarre, ritualistic orgy. And then there are the strange things he's been seeing - glimpses of people with their bodies contorted impossibly out of shape... Is Bill going mad or is there something seriously amiss in his neighbourhood?
