Steve Martin is dentist Robert Sangster trapped in a too safe relationship with his hygienist (Laura Dern). When he takes a walk on the wild side with drug-dealing patient Susan Ivey (Helena Bonham Carter), Sangster's pharmaceutical supplies are pilfered and Ivey's psychopathic brother and the police send his life into tailspin. A laboured attempt to reinvigorate an increasingly tired-looking Martin.
