Steeped in the glamour of 1960s Hollywood, Die Mommie Die! stars playwright Busch as Angela Arden, a fallen pop diva trapped in a hateful marriage to film producer Sol Sussman Bob Ari. Desperate to find happiness with her younger lover, an out-of-work TV actor named Tony Parker Chris Hoch, Angela gruesomely murders her husband with the aid of a poisoned suppository. Angela's manipulative daughter, Edith Ashley Morris, convinces her "emotionally disturbed" brother, Lance Van Hansis, that together they must avenge their father's death —by killing their mother! Kristine Nielsen rounds out the cast as the Sussmans' live-in maid, Bootsie Carp.
