Gumshoe Rigby Reardon (Steve Martin) takes on the case of a missing cheese maker/scientist when the man's shapely daughter, Juliet Forrest (Rachel Ward), hires the detective to investigate. In this film-noir spoof directed by Carl Reiner, Reardon interacts with a host of Tinseltown legends -- including Humphrey Bogart, Kirk Douglas, Burt Lancaster, Ingrid Bergman, Lana Turner and Joan Crawford -- in clips intercut from vintage detective films.
