Nobody Lives Forever (1946) is a returning veteran swindler confidence-man romance drama film noir which like many prime examples of the style from the 1940s discusses the impossibility of going straight and escaping one's past in post-WWII American society that is noir as hell and a constant fateful threat, never to be reconciled with the American Dream.
Nick Blake (played by John Garfield) is a charming and roguish ex-con artist who has just been released from prison. He decides to go straight and live an honest life. However, he is approached by his former partner-in-crime, Doc, with an opportunity for a lucrative con job. The target is a wealthy widow, Gladys Halvorsen (played by Geraldine Fitzgerald), who is seeking companionship and may be susceptible to Nick's charms.
Nick reluctantly agrees to participate in the scheme, but as he spends more time with Gladys, he begins to genuinely fall for her. The two develop a romantic connection, complicating Nick's plans to deceive her. As the con unfolds, Nick faces internal conflicts between his desire for a new, honest life and the pressures of his criminal past.
