A gallery of high-living lowlifes will stop at nothing to get their sweaty hands on a jewel-encrusted falcon. Detective Sam Spade (Humphrey Bogart) wants to find out why - and who'll take the fall. This third screen version of Dashiell Hammett's novel is a film of firsts: John Huston's directorial debut, rotund Sidney Greenstreet's screen debut, film history's first film noir and Bogart's breakthrough role after years as a Warner contract player.
