As the private eye of private eyes, Steve Martin is Rigby Reardon. He's tough, rough and ready to take on anything when Juliet Forrest appears on the scene with a case: her father, a noted scientist, philanthropist and chesemaker, has died mysteriously. Reardon immediately smells a rat and follows a complex maze of clues that lead him to the "Carlotta Lists." With a little help from his "friends" Reardon gets his man. An exciting action-fun packed film the way '40s films used to be!
