As the private eye of private eyes, Steve Martin is Rigby Reardon. He's tough, rough and ready to take anything when Juliet Forrest (Rachel Ward) appears on the scene with a case: her father, a noted scientist, philanthropist and cheesemaker has died mysteriously. Reardon immediately smells a rat and follows a complex maze of clues that lead to the "Carlotta Lists".
With a little help from his "friends", Alan Ladd, Barbara Stanwyck, Ray Milland, Burt Lancaster, Humphrey Bogart, Charls Laughton, etc., Reardon gets his man. An exciting, action-packed film the way 40s' films used to be!
