Sandra Bernhard 's outrageous one-woman show deals with many normally taboo subjects and controversy runs through her personal life: she was once Madonna's lover and is a lesbian pin-up, but she also posed for Playboy. In this country, however, she is perhaps best known as the bisexual Nancy in the Channel 4 comedy Roseanne. Bringing together archive clips, footage of her sell-out New York show and interviews, this sometimes explicit film explores how Bernhard has become a cult icon of female sexual power.
