In The Maltese Falcon (1941), Humphrey Bogart plays Sam Spade, a private eye detective who is lured into the chase for a bird statue by a mysterious and deceitful woman named Ruth. His objectives are to find the Maltese Falcon, and discover the murderer of two crimes: the death of his former partner, Miles Archer, and another man named Thursby. He also wishes to prove his innocence for the murder of his partner because the police have him as the prime suspect. Sam approaches these problems by using his street smarts and investigative skills to follow a trail.
