Henry Hearst, portrayed by Gene Hackman, finds himself in a precarious situation just before delivering a significant speech at an exclusive gathering in Puerto Rico. He is summoned to the police station to answer questions regarding the discovery of a young girl's body, who had been brutally raped and murdered the previous day. Leading the inquiry are Victor Benezet, played by Morgan Freeman, and the younger Detective Felix Owens (Thomas Jane). As the interrogation unfolds, Hearst's accounts shift repeatedly: he was jogging with a neighbor's dog, he stumbled upon the girl, or perhaps the dog made the discovery. With each inconsistent statement, the police begin to suspect him of the heinous crime.
Under pressure from his superior, Miguel Ángel Suárez, Benezet is coerced into letting Hearst go, despite lacking concrete evidence against him. Meanwhile, at the party, whispers circulate among the attendees, as Chantal Hearst (Monica Bellucci), Henry's wife, struggles to maintain her composure. She faces her own round of questioning after her husband's speech, especially about the couple's arrangement of sleeping in separate rooms, which raises many eyebrows.
As the night progresses, the narratives from both Henry and Chantal begin to unravel. Initially blaming Chantal for her jealousy, Hearst's secrets start to emerge: his proclivity for cheap, very young prostitutes, and allegations that Chantal is involved with her sister's husband, the artist Paco Rodríguez (Luis Caballero). Chantal’s version of events becomes increasingly shocking as she mentions witnessing her husband attempt to seduce her niece, Camille (Isabel Algaze), and even washing blood-stained clothes under the cover of night.
The mounting pressure forces Chantal, the official owner of their mansion—a gift from Henry—to authorize a deeper investigation by the police. As they scour their home, the detectives uncover disturbing photographs of the murdered girls alongside previous snapshots. With his back against the wall, Henry panics, suggesting that Chantal has set an elaborate trap for him. His hesitancy to divorce her stems from the fear of losing half of everything he owns, including the mansion.
In a tense turn of events, Hearst finally starts to relay the truth. However, just as Benezet gains a glimmer of hope, he is interrupted by news that the true murderer has been apprehended in a car, caught attempting to target another young girl, with incriminating video evidence found inside. Consequently, both Benezet and Owens release Hearst from suspicion.
Despite his exoneration, a rift remains unbridged; Henry cannot absolve Chantal of trying to frame him. The implications of this twisted story leave an unsettling mark as the truth battles perceptions, ultimately culminating in an ambiguous ending that invites interpretation.
