On Mother’s Day in Taipei, Chen Mo makes a dinner date with his wife, hoping to improve their estranged relationship. While buying a cake on his way home, a car double-parks next to his, preventing his exit. For the entire night, Chen Mo searches for the owner of the car and encounters a succession of strange events and eccentric characters: an old couple living with their precocious granddaughter who has lost their only son; a one-armed barbershop owner cooking fish-head soup; a mainland Chinese prostitute trying to escape her pimp’s cruel clutches; and a Hong-Kong tailor embroiled in debt and captured by underground loan sharks.
