Johnny Clay, a former prisoner, plans a big hit: taking over the huge sum, kept in the offices of a racecourse on an important day of racing. The plan is studied in all its details, and each of the accomplices is entrusted with a task. The main perpetrators are four, Kennan, a policeman beset by the need to pay gambling debts; O'Reilly, a bartender who has a sick and needy wife, Unger, an old alcoholic bookmaker; Peatty, a modest cashier of the racecourse, victim of unrequited love for his wife, Sherry, an ambitious and greedy woman. There are also two collaborators who don't know Johnny's plan. The predisposed gears work perfectly and Johnny manages to get his hands on a two couple of million dollars.In the established place the accomplices are waiting for Johnny to share the spoils. Instead of the boss, an armed young man shows up: he is Sherry's lover, the cashier's wife, who, having learned of the company, wants to take over the huge sum. A shooting takes place, in which everyone is killed, minus Peatty, who finds the strength to run home to kill his wife. Johnny, realizing the massacre, tries to escape by airplane with the spoils, together with his fiancée, but the old suitcase, in which he closed the stolen banknotes, falls to the ground, opens and the tickets disperse, pushed in every direction by the powerful breath of the engines of an airplane. The unexpected blow takes away from Johnny any possibility of reaction and he lets himself be arrested without resisting.
