Johnny Clay, portrayed by Sterling Hayden, is a man with a plan, determined to execute a sophisticated heist to steal $2 million from a racetrack. Recently released from prison, Johnny teams up with a diverse group of accomplices, each with their own desperate motivations. Among them is the race track cashier, George Peatty, played by Elisha Cook Jr., who is struggling to manage his controlling and self-absorbed wife, Sherry, brought to life by Marie Windsor. Ongoing complications arise, as Sherry is entangled in an affair with mobster Val Cannon, a role taken on by Vince Edwards, who is secretly plotting to take George out of the picture so he can abscond with Sherry—and her husband's money.
While George's desperate need for cash stems from his frustrated married life, the barman Mike O'Reilly, played by Joe Sawyer, has his own reasons to get a cut of the action: he requires money to take care of his ailing wife. The crooked policeman Randy Kenna, portrayed by Ted de Corsia, is further revealed to be in deep with local bookies due to persistent gambling debts. Marvin Unger, played by Jay C. Flippen, acts as the financier of the operation, emphasizing the growing tensions within their ranks as the stakes rise.
As Johnny and his team meet to iron out the details of their extravagant heist, the drama escalates when George discovers Sherry eavesdropping on their discussions. He quickly puts her in her place but recognizes that her greed could compromise their plan. Johnny, instinctively aware of Sherry's manipulative nature, proposes to her that she will receive a generous cut of the loot if the operation proceeds smoothly. Yet, true to her opportunistic ways, Sherry confides in Val about the heist, initiating a dangerous game of double-crossing.
To bolster their heist, Johnny recruits Nikki Arane, played by Timothy Carey, a ruthless gunman, and Maurice Oboukhoff, who serves as a diversion during the critical moment of the robbery. As the stage is set on the day of the race, chaos ensues with Maurice starting a brawl at Mike's bar, which draws the attention of security while George skillfully opens the office door. Johnny, equipped with a shotgun concealed in his locker, puts the payroll clerks in a desperate standoff.
> “What’s the difference?” Johnny declares as he and Fay realize their plans are spiraling out of control.
In the heat of the moment, Johnny successfully secures the money and orchestrates an escape, but not without dramatic turmoil—the racehorse Red Lightning is shot, prompting police to respond swiftly, resulting in a fatal reckoning when Nikki faces a deadly confrontation with law enforcement.
As Johnny prepares to meet his accomplices at his apartment, tensions run high when they are ambushed by Val and his cohorts, leading to a catastrophic gunfight that leaves all but George dead. Mortally wounded, George ultimately confronts Sherry, bitterly realizing her deceit before he succumbs to his injuries.
In a fateful twist, just as Johnny and his fiancée Fay plan to escape town, they encounter further misfortune at the airport. After checking in the large suitcase filled with their hard-earned money, it fatefully spills its contents across the runway when an accident occurs. In a frantic attempt to secure their escape amid the mounting police presence, Johnny grapples with the frailty of their ambitions and the undeniable consequences of their ill-fated decision-making. The story concludes with a palpable tension as Johnny and Fay’s hopes of a fresh start hang precariously in the balance against the backdrop of chaos unraveling at the airport.
