Plot
Danny Haley is an owner of an illegal gambling location that the police raid even though he pays the police for protection. Danny hangs out at a café where he listens to singer Fran Garlan. Fran is in love with Danny but Danny tells her that he cannot commit to a relationship and that she is just a girlfriend.
Later that evening at the café, Danny meets businessman and Air Force veteran Arthur Winant, who is in town to buy some equipment for a sports club. When Danny notices a check for $5,000 in Winant's wallet, he invites Winant to play poker at his closed establishment with Danny's pals Soldier, Barney and Augie. During the game, Winant talks about his older brother Sidney, who is coming to meet him late the next evening. Barney and Augie let Arthur win $325, but the next evening, they cheat Arthur out of all his money and the $5,000, which is not his.
The next day, Danny learns that Winant has committed suicide. Fearing police attention, Danny tells his friends to wait a few days before cashing Winant’s check. Barney, the most nervous of the group, thinks that someone is following him, and the next morning he is found dead.
Police captain Garvey interviews Danny and Augie and tells them that he knows that there is a connection between Winant's death and the poker game, and that Winant left a letter for his brother Sidney. He informs them that Sidney is a dangerous criminal and likely to avenge his brother's death, and that Barney was probably killed by Sidney. Danny and Augie deny any connection with Winant's death.
Danny and Augie try to find Sidney before he finds them. In Los Angeles, Danny poses as an insurance agent and visits Winant's widow Victoria, telling her that he needs to locate Sidney, the beneficiary of Winant's life-insurance policy, and that Victoria will be the beneficiary if Sidney is not found. Victoria cannot provide a photo of Sidney because she has destroyed them. Danny spends a romantic evening with Victoria, but when he reveals his true identity, she then chases him out in a rage. Danny tries to give her Winant’s check, but she refuses to accept it.
Returning to his motel, Danny finds Augie's body hanging from the shower in his room. The police arrest Danny after the hotel manager tells them that he heard both men arguing loudly the day before. Captain Garvey arrives in Los Angeles and, believing Danny to be innocent, persuades the local police to release Danny, provided that he immediately leaves the city.
Danny travels to Las Vegas, where Soldier works at a casino. Soldier gets Danny a job as a blackjack dealer. Fran comes to Las Vegas, and Soldier finds her a job as a singer in the casino's lounge.
After work one day, Danny goes to a nearby casino to play craps and builds a small stake into more than $10,000. Victoria phones and warns Fran that Sidney knows that Danny is in Las Vegas. Danny asks Fran to send the money that he had won to Victoria the next morning if anything should happen to him. Believing that Danny is in love with Victoria, Fran decides to leave for Chicago.
Danny waits in his motel room with a gun in his hand. However, Sidney emerges from the bathroom, catching Danny by surprise; after a struggle, he chokes Danny. Captain Garvey and his men, who were following Danny all along, burst into the room and shoot Sidney.
The next morning at the airport, Danny catches Fran before she boards her plane to tell her that he loves her. They kiss and walk back into the airport.
