From the wondrously fertile mind of writer/director John Waters A Dirty Shame tells what happens when a horny horde of 'sex addicts' invades a blue-collar neighbourhood to the shock & dismay of the neighbours. Sylvia Stickles (Tracy Ullman) grumpy repressed & middle-aged doesn't like sex. Her handsome husband Vaughan (Chris Isaak) still has marital urges but Sylvia couldn't be less interested. She is in complete contrast to her exhibitionist daughter Caprice (Selma Blair) a go-go dancer with stupendously enlarged breasts! Everything changes when Sylvia is involved in a freak accident & receives a head injury. Sexy tow truck driver Ray-Ray Perkins (Johnny Knoxville) rushes to her aid & Sylvia realises he's no ordinary service man; no he's a sexual healer who knows how to bring out her flaming cauldron of hidden lust A prude no longer Sylvia suddenly views the world through hypersexual eyes. She seeks out Ray-Ray at his garage & discovers that she is not alone. Other head injuries have brought forth a flock of sex addicts who have infiltrated every corner of the community. Sylvia & Vaughan's marriage is jump-started by a new sex act that elevates the community into a whole new dawn of sexual awakening.
