THE HOT SPOT

Drifter Harry Madox takes a job as a used car salesman in a small Texas town. In the summer heat, he develops an interest in Gloria Harper, a young demure woman who works at the car dealership in the loan office. He notices Gloria's legs, and her shoes which have wooden fruit on them. Dolly Harshaw, who is married to the dealership's owner, flirts shamelessly with Harry, telling him that she has a pair of shoes exactly like Gloria's. Soon after they begin a torrid affair.

Harry learns that the staff of the local bank are all volunteer firemen and that the cameras in the bank do not work. After careful planning, he sets a fire in a building across the street to lure them all away and while they are gone, he robs the bank. His conscience forces him to enter the burning building to save a homeless man trapped inside. Despite this the town's sheriff suspects Harry of committing the robbery and he is arrested. He learns the money is useless anyway as the serial numbers were recorded. Dolly gives him an alibi and tells him she will sell him out unless he kills her husband, whom she married for his money. When he refuses, Dolly threatens to expose him. She ultimately kills her husband herself by overstimulating his weak heart during a vigorous sexual encounter.

Meanwhile, Harry discovers that Gloria is being blackmailed by a local criminal named Frank Sutton. Sutton has nude photographs he took of Gloria and her best friend Irene Davey, after following them down by the local swimming hole, having heard tell of Irene being with another woman, who was her former teacher. Irene killed herself after being blackmailed and Harry, who has fallen in love with the 19-year-old Gloria, confronts Sutton to get the pictures. The tense conversation escalates into a fight, and Harry severely beats Sutton, but he defiantly continues to blackmail Gloria. Harry visits Sutton at his home and finds him having sex with a woman having wooden fruit shoes exactly like those belonging to Gloria. As Harry and Sutton begin fighting the unknown woman escapes, suffering an injury to her face. Harry ends up killing Sutton in the ensuing struggle. He plants the stolen money to divert suspicion away from himself, and disposes of the shoes, believing they belong to Gloria. He then tells the police that Sutton, who had no job and few assets, had recently paid cash for a new car, making it seem that Sutton had robbed the bank. The serial numbers tally and Harry receives the promise of a hefty reward for providing the tip that helps the police "solve" the robbery. He plans to marry Gloria and take her to the Caribbean Islands.

After being called over by the new business owner, Dolly, to the Harshaw house, Harry notices as they arrive that Gloria is wearing her wooden fruit shoes. Then Harry seeing the fresh scar on Dolly's face realizes that it was her and not Gloria who was having sex with Sutton. Before he can maneuver, Dolly ruins Harry's plans by showing him a copy of a certified letter she says she has entrusted to her attorney, to be opened in the event of her death. The letter is a firsthand account that will implicate him in the bank robbery, in Sutton's death, and records Gloria's embezzlement, information she had from Sutton. Dolly tells Gloria that Harry told her she was using company funds to pay off Sutton. Dolly then tells Gloria that she won't go to the police and that she can keep her job at the car dealership to pay back the money she stole. Believing she has been played for a fool, a heartbroken Gloria leaves Harry. Trapped, enraged, Harry tries to strangle Dolly, but cannot bring himself to kill her. Harry resigns himself to life with Dolly, and leaves town with her.

Harry’s plans unravel when Dolly, now in control, reveals evidence tying him to the crimes and destroys his hopes for escape with Gloria.

The ending cements the film’s noir credentials: Harry, who tried to outmaneuver both the law and his lovers, is ultimately undone not by justice, but by the manipulations and secrets of those closest to him. The final twists highlight how the symbols and desires that once seemed empowering become traps, locking each character into the consequences of their own schemes.
