A police commissioner, Holger, Mikael Birkkjær tells his daughter the cautionary tale about marriage: the story of Christian Holm Dar Salim Holm and Leonora Holm Sonja Richter Holm. The film opens by framing their era as a quiet, ordinary life that hides a volatile undercurrent, with Christian, a contractor, working alongside his friend Peter Morten Burian. Leonora is a devoted housewife who put her promising violin career on hold years ago to care for their son, Johan, who is now in remission and preparing for high school graduation. From the outside, it looks like a stable, loving household, but the fissures are already forming beneath the surface, waiting to erupt.
One night, a 4 AM text allegedly from Peter unsettles the couple. When Leonora Holm demands to see the message, Christian hurls his phone against the wall in a burst of anger. The tension intensifies at an office party, where Xenia Sus Wilkins is revealed to be more than just a coworker to Christian, as he is seen with her in a compromising moment, eyes locked in a stark gaze that makes Leonora’s suspicions hard to ignore. The revelation of this affair shatters trust and sets the stage for a careful, deadly game of brinkmanship between the two spouses.
When Christian tries to end things with Leonora, she insists on a breakup on her terms. If he refuses, she threatens to expose embezzlement from his company used to pay for Johan’s treatments. Christian searches for leverage by learning from an old school friend that Leonora once had a boyfriend named Mike, who died under mysterious circumstances after an outdoor party. This revelation fuels a dangerous paranoia in Christian, and a confrontation about Mike spirals into a chilling accusation that pushes Christian to a breaking point. He waits along Leonora’s usual route one night, and in a desperate bid to push her away, he strikes her with a company van—an act that shocks them both and that Leonora narrowly survives, while she later discovers he has washed the van, seemingly trying to erase the evidence.
In the wake of this near-tragedy, Christian pretends to have broken things off with Xenia and decides to stay with Leonora. After Johan’s graduation, Christian briefly considers turning himself in to the police, but the couple’s web of deceit deepens as investigators begin to scrutinize them. Leonora, however, uncovers a darker truth: she killed Mike years ago, and Christian’s supposed alibi starts to unravel. The couple’s strategy shifts to a coordinated murder plot against Xenia, driven by the belief that if Christian cannot leave, he will not be able to hurt Leonora again if he is tied to someone else.
To orchestrate a seemingly airtight alibi, they check into a spa resort. Christian slips away to Xenia’s allotment, while Leonora creates a convincing cover by playing back a recording of Christian speaking and sending a breakup text from his phone to Xenia—an eerie, premeditated ploy to secure an emotional alibi. At the allotment, Christian reconciles with Xenia, and the two engage in sex. Afterward, Xenia goes to the bathroom where Leonora calmly, methodically stabs her to death. The couple’s crime is not yet complete, and the investigation tightens as the police commissioner and his partner search the apartment for clues; the room is disturbingly clean, and Xenia’s whereabouts become the missing puzzle piece.
The investigators pressure Christian and Leonora, and Christian admits to the affair, claiming to have broken things off with Xenia via text while at the spa. Suspicious, the cops deploy dogs to comb the surrounding area. During a Sankt Hans celebration, Christian encourages his friend Kim to light the bonfire early, a pivotal moment that could expose their ruse. As the dogs arrive and begin to bark near the bonfire, the commissioner realizes they may have hidden Xenia’s body in the blaze. In a tense, final twist, Christian stokes the flames before the authorities can intervene, watching with Leonora as the fire consumes what remains of Xenia.
The story that the commissioner has been telling his daughter is not merely a crime tale; it’s a cautionary parable about the fragility of trust and the perilous dynamics of marriage. In the final, haunting image, it is revealed that, somewhere in a foreign country, a grieving Christian discards Xenia’s remains into the water, the punishment and consequence of their choices echoing in perpetuity. Through a web of deceit, jealousy, and calculated violence, the couple’s downfall unfolds, leaving the audience to weigh the costs of passion and the limits of forgiveness.
