Triple bill of crime classics. In 'The Big Sleep', private detective Philip Marlowe (Humphrey Bogart) agrees to rid a wealthy family of a blackmailer who is threatening the younger daughter, but the man is killed before he can act. Drawn nevertheless into the Sternwood family's problems (not least because of his attraction to the elder sister, played by Lauren Bacall), Marlowe uncovers drugs, murder and more blackmail. In 'Key Largo', Frank McCloud (Bogart) is staying at a run-down hotel on an isolated Florida island, Key Largo, when it is taken over by a gangster (Edward G. Robertson) and his entourage, on the run from deportation. An impending hurricane gives McCloud the opportunity and courage to take things in hand and lure the gangster to his death. In 'The Maltese Falcon', Sam Spade (Bogart) is a cynical private eye caught up in the hunt for a jewel-encrusted falcon while searching for the murderer of his partner, Miles Archer (Jerome Cowan). His fellow treasure hunters include a sinister little and large act (Peter Lorre and Sydney Greenstreet), a psychotic tearaway (Elisha Cook Jnr) and a duplicitous femme fatale (Mary Astor).
