Roberta (Rosanna Arquette) seeks vicarious thrills through other people's personal ads. But via a jacket, amnesia and mistaken identity, Roberta comes to believe she's Susan (Madonna), a wild Soho vamp wanted by the mob. Dez (Aidan Quinn) falls for "Susan" (Roberta); the real Susan has no idea she has a double; and Roberta's husband, Jim (Mark Blum), is thrown for a loop. Director Susan Seidelman's romantic comedy features tons of cameos.
