The following is adapted from a review I wrote back in 2007 for a David Lynch Blog-athon.
Bill Pullman plays a saxophonist who kills his wife (Patricia Arquette) because she was apparently cheating on him, and is so guilty over the murder that while in prison he goes insane and creates another reality for himself, one in which he’s a young mechanic (Balthazar Getty). Pullman’s fantasy world is something out of the 50s or early 60s of American Graffiti, with its car obsessions, pleasant suburban family, and the cute girl next door (Natasha Gregson Wagner). Unfortunately for Pullman, his subconscious won’t quite let him forget his crime, and soon Getty’s hanging around with a gangster (Robert Loggia) and his femme fatale girl (Arquette again). As in a typical film noir, Getty falls for the bad girl, conspires with her to commit some crimes (including a murder or two) and comes to a bad end.
