Harry Madox, a drifter, arrives in a small Texas town to work as a used car salesman. Set against the backdrop of scorching summer heat, his attention quickly shifts towards Kaho, who plays Yumi Isomura, a modest young woman working in the dealership's loan office. Harry becomes intrigued by her, especially noticing the details of her appearance, such as her legs and her distinctive shoes decorated with wooden fruit. This modest attraction soon sparks a complex and intense relationship with Dolly Harshaw, portrayed by Maki Sakai, the wife of the dealership’s owner. Dolly, who is openly flirtatious, boldly confesses that she has shoes identical to Yumi’s. Their flirtation quickly ignites into a passionate and tumultuous affair, filled with secretive meetings and mounting tension.
As Harry delves deeper into his surroundings, he uncovers that the local bank’s staff are all volunteer firemen, and surprisingly, the bank’s security cameras are nonfunctional. This discovery prompts Harry to devise a risky plan: he sets a fire across the street to distract the firefighters. While they are occupied battling the blaze, Harry takes the opportunity to rob the bank. His conscience later prompts him to enter the burning building to rescue a homeless man trapped inside, showing a hint of moral conflict amid his criminal actions. Unfortunately, despite his efforts, Harry is soon suspected of being the robber by the town’s sheriff and ends up getting arrested.
In the aftermath, Harry learns that the stolen money is worthless because the serial numbers have been recorded. Dolly, seeking to protect herself, provides him with an alibi and warns him that she will betray him unless he kills her husband, whom she married solely for his wealth. When Harry refuses, Dolly takes matters into her own hands by killing her husband during a vigorous sexual encounter that overstimulates his weak heart—an act of manipulation and murder intertwined.
Meanwhile, Harry becomes aware that Gloria, the young woman he is attracted to, is being blackmailed by a man named Naoki Tanaka, who has nude photographs of Gloria and her best friend Irene Davey, played by Anne Suzuki. Sutton, the blackmailer, followed Gloria and Irene at a swimming hole after hearing rumors about Irene’s previous relationship with a woman, and subsequently exploited their vulnerability. Irene tragically committed suicide after being blackmailed. Deeply falling in love with Gloria, Harry confronts Sutton, leading to a heated fight where he beats Sutton severely but fails to stop him from continuing to blackmail Gloria.
Harry's confrontation with Sutton takes a darker turn when he finds Sutton having sex with a woman wearing shoes exactly like Gloria’s. In the ensuing chaos, Harry kills Sutton during the struggle. To cover his tracks, Harry plants the stolen money at Sutton’s house, suggesting Sutton was the bank robber, especially since Sutton had recently paid cash for a new car—an unusual detail that helps Harry frame him. He then disposes of Gloria’s shoes, believing they belonged to her, and fabricates evidence linking Sutton to the crime. Harry reports Sutton as the mastermind, leading the police to believe they’ve solved the bank robbery, and Harry is rewarded with the promise of a significant payout for his "tip."
Harry’s plans with Gloria appear promising—he hopes to marry her and take her to the Caribbean. However, suspicions deepen when, during a visit to the Harshaw house, Harry notices that Gloria is wearing her wooden fruit shoes. This realization coincides with his discovery of a scar on Dolly’s face, revealing that she was the woman Sutton was with and not Gloria. Before Harry can act, Dolly unveils a sealed letter, revealing her knowledge of Harry’s crimes and threatening to expose him. The letter implicates Harry in the bank robbery, Sutton’s death, and Gloria’s embezzlement—information she obtained from Sutton.
Dolly's threats devastate Gloria, making her believe she has been manipulated and fooled. Angered and heartbroken, Gloria leaves Harry. Facing a tragic choice, Harry nearly strangles Dolly in a fit of rage but ultimately cannot bring himself to kill her. He resigns himself to a life entangled with Dolly, leaving town with her, haunted by the web of lies, betrayal, and moral compromise that have defined his stay in the small Texas town.
