The Killers (1946)

Two hit men walk into a diner asking for a man called "the Swede" (Burt Lancaster). When the killers find the Swede, he's expecting them and doesn't put up a fight. Since the Swede had a life insurance policy, an investigator (Edmond O'Brien), on a hunch, decides to look into the murder. As the Swede's past is laid bare, it comes to light that he was in love with a beautiful woman (Ava Gardner) who may have lured him into pulling off a bank robbery overseen by another man (Albert Dekker).
