From the outrageous John Waters, writer-director of Pink Flamingos and Hairspray, comes another signature exercise in bad taste. Sylvia Stickles (Tracey Ullman), the owner of a convenience store in a working-class Baltimore neighborhood, suffers a concussion. The injury causes a drastic change in her sexual drive, turning her into a sex addict with crazy, wild and urgent desires and compulsions, much to the joy and then frustration of her husband (Chris Isaak), who has trouble keeping up with her. As Sylvia's insatiable libido reaches fever pitch, her new oversexed personality threatens to tear apart the remnants of what wasn't an entirely perfect family to begin with. And that's A Dirty Shame.
