Gloria, a single mother and morgue worker, signs up for an online dating service on a friend's suggestion. She goes on a date with Michel, a charming shoe salesman, and their connection is immediate. They share an intimate night at Gloria's apartment, marking the start of a complicated relationship.

Over time, Michel becomes a fixture in Gloria's life and grows close to her daughter. She lends him money for a business emergency, hoping to help him get started. When he disappears with the cash, Gloria tracks him down and finds him flirting with other women at a nightclub.

Gloria confronts Michel after discovering photos of his previous victims, including a picture of Gloria herself. He explains that he was sexually abused by his mother and now uses his sexuality to seduce and scam women. The revelation deepens Gloria's fascination with his lifestyle rather than ending the relationship.

Craving the thrill of Michel's dangerous lifestyle, Gloria decides to stay involved and helps him. She leaves her daughter with a trusted friend so she can participate more fully in his schemes. The partnership deepens as they become conspirators in their own dynamic.

Michel marries Marguerite, his new victim, while Gloria poses as his recently divorced sister. The three of them cohabit, and Gloria grows increasingly jealous and possessive of Michel and Marguerite's closeness. The volatile trio advances their dangerous arrangement.

Gloria's jealousy erupts when she witnesses Marguerite's intimacy with Michel, and she kills Marguerite in a fit of rage. The act marks a brutal escalation in the couple's shared crime and Gloria's grip on the situation. After the murder, Michel remains by her side, complicit in the deception.

Shortly after Marguerite's death, Gloria kills another one of Michel's victims after watching them have sex. Following the act, Gloria and Michel marry each other in an unofficial ceremony, cementing their partnership. The killings continue to intertwine with their personal bond.

Solange, Michel's next intended target, lives with her daughter on a remote farmhouse. She confides that she is pregnant with Michel's child, despite his promise not to be intimate with new victims. Gloria's jealousy and ambition push events toward a violent climax.

Furious, Gloria gives Michel a hatchet and forces him to kill Solange to avoid exposure. Solange's daughter witnesses the murder and flees in fear, leaving Gloria and Michel to contend with the aftermath. The plan seems to work only as a temporary control for Gloria.

Solange's daughter escapes the scene and runs for safety after witnessing the killing. Michel intervenes to stop Gloria from harming the girl, but the intervention sows further tension between them. The couple's fragile balance begins to tilt toward tragedy.

In a burst of rage, Gloria turns on Michel and tries to drown him in the lake, then leaves him to die and walks back home. She calls her daughter to tell her she loves her, signaling a complicated mix of affection and danger. She later gathers her clothes and notices medication as she contemplates the future.

Sometime later, Michel and Gloria bathe each other, a moment that suggests reconciliation and a renewed bond between them. They dress carefully and elegantly afterward, attempting to recapture their earlier appearances. The uneasy partnership persists as they head toward a shared night out.

The couple dresses in their finest clothes and quietly sets out as if nothing malicious has happened. They prepare for a night at the cinema, presenting a polished exterior to the world. The tension underneath remains unresolved.

They take their seats at the cinema, and Michel notices people with flashlights moving through the theater. The unusual sight suggests that Michel is being hunted for the murders. He remains tense, staring straight ahead as the lights sweep by.
