Michael Schultz directed this kinetic, hyperventilating comedy (scripted by Joel Schumacher) concerning the crazed events that go on within a single 10-hour period at a Los Angeles car wash. The cast of colorful car-wash employees includes Lonnie (Ivan Dixon), an ex-con; Duane (Bill Duke), a militant black activist; and Lindy (Antonio Fargas), an obnoxious homosexual. Sully Boyar plays Mr. B, the frazzled car-wash owner who has to deal with his screwball employees along with his over-educated slip of a son, Irwin (Richard Brestoff), who quotes Mao and wants to radicalize the workers. Also along for the wash and wax are Miss Beverly Hills (Lauren Jones), with a wild assortment of wigs; Marsha (Melanie Mayron), the distracted car wash secretary; a mad bomber (Prof. Irwin Corey), who is terrorizing the neighborhood; and Daddy Rich (Richard Pryor), the founder of the Church of Divine Economic Spirituality, who sports a gold limousine.
