In Phoenix, Arizona, Harry Collins is a cop whose compulsive gambling has indebted him to a local gangster, Chicago. As his losses mount and time counts down, Collins resorts to exploiting a young woman, Veronica, that he has picked up to distract his friends in a poker game. Despite the successful distraction, he still loses, and he rejects Veronica’s sexual advances, as he considers her to be bad luck. When Collins drops her off at her house, Veronica’s mother sees her daughter in tears and glares at Collins. Collins later tracks down Veronica’s mother, Leila, and defends himself, stating that he did not have sex with her. Unimpressed, Leila rebukes him, which causes him to reassess his behavior and offer a sincere apology. Surprised by his apology, Leila slowly warms to Collins, and they begin a romance. Having lost his lucky lighter, Collins asks her for a keepsake, but Leila tells him that he must make his own luck and avoid whatever trouble in which he’s become involved.
Meanwhile, Chicago cuts off Collins from his bookies and gives him 48 hours to either repay his debt or murder Joey, a young suspect held in custody. Mike Henshaw, Collins’ corrupt partner, suggests murdering Chicago, but Collins, unwilling to welch on a bet or murder Joey, decides instead to rob Louie, a local loanshark. Collins recruits Henshaw and another corrupt cop, James Nutter, and, over their objections, brings in a more straight-laced cop, Fred Shuster. Unknown to the others, Shuster has discovered that his wife, Katie, is having an affair with Henshaw. Distraught and feeling betrayed, Shuster agrees to work with Lt. Webber to bring down the corrupt cops. However, the robbery is botched when the trigger-happy Henshaw kills Louie before he can open the safe. Collins hires a local locksmith to crack Louie’s safe, and the group splits up. Collins and Shuster arrive at the meeting point, but Lt. Webber is already there; Webber betrays Shuster, killing him, and shoots Collins in the gut. Collins escapes, but Webber steals the money.
Nutter and Henshaw, suspecting that Collins has betrayed them, arrive at the meeting point and discover Shuster’s body. Before they can track down Collins and kill him, they are surrounded by the police. When Nutter attempts to surrender, Henshaw kills him; Henshaw is killed in turn by the other cops. Collins hitches a ride back to town and surprises Katie and Webber, who are having an affair. Over their objections, Collins burns most of the money while denouncing them both for betraying Fred. After alerting the cops to Webber’s involvement, Collins takes enough money to pay off his gambling debt and meets with Chicago. Amused, Chicago accepts the money but mocks Collins’ reluctance to murder Joey; Chicago reveals that he has had Joey murdered in prison and points out that had Collins simply murdered Joey, all of this trouble could have been avoided. Enraged, Collins kills Chicago and his bodyguards, then stumbles back to his car, where he apparently dies of his wounds.
It’s a well shot film, neatly edited, with excellent performances from the entire cast.
