French Twist

A campervan breaks down in front of Laurent and Loli's house in southern France. Marie-Jo, a DJ, asks to use their phone and, in exchange, Loli helps fix her blocked sink. What begins as a simple favor soon turns into an intimate connection between Loli and Marie-Jo.

Antoine inadvertently reveals Laurent's infidelity to Loli. Loli confronts the truth and begins to consider Marie-Jo's presence more seriously. Marie-Jo moves into the home, changing the household's dynamic.

Laurent suggests letting Loli pursue the affair without hostility and wait for it to burn out. Loli accepts the arrangement, and the two women gradually form a three-way household dynamic. The atmosphere at home feels oddly serene on the surface.

Another lesbian couple, old friends of Marie-Jo, visits and is welcomed into the home. Loli grows increasingly annoyed and jealous as the group dynamics intensify. Laurent watches the tension rise while maintaining the façade of harmony.

Marie-Jo decides the arrangement won't work and makes a deal with Laurent: she will leave if Laurent helps her become pregnant. Laurent agrees to have sex with Marie-Jo to make her pregnant. Afterward, Marie-Jo departs, leaving Loli and Laurent to deal with the consequences.

Laurent and Loli return to their previous routine, but the relationship has been changed by the pregnancy and secrets. Laurent tells Loli nothing about Marie-Jo's departure. The household is now a quieter, more complicated version of its former self.

A mutual acquaintance reveals that Marie-Jo is living in Paris and is several months pregnant. Loli and Laurent decide they must confront the situation directly and travel to Paris. They hope to understand what Marie-Jo has wanted and why.

In Paris, they find Marie-Jo working as a DJ in a lesbian club. Their intrusion triggers a quarrel with the club owner, and Marie-Jo is fired. Loli and Laurent arrange to bring her back to their home for the baby.

Marie-Jo returns to their home with her baby; the two mothers resume caring for their children in the familiar setting. The atmosphere mixes tenderness with unresolved tension as the family adapts to the new reality.

The arrangement persists with both mothers sharing responsibility for the children. Laurent begins to search for a bigger house to accommodate the growing family. The emotional ties deepen, even as jealousy remains a possibility.

While house-hunting, Laurent meets a handsome Spaniard selling a house and they share a breakfast together by the pool. They exchange glances and end up sharing a kiss by the pool. The encounter hints at new desires that could disrupt the trio's balance.

Laurent's kiss with the Spaniard signals potential changes to the relationship. The trio remains bound by their children, but the future is uncertain as new romantic possibilities loom. The film ends on a note of unresolved tension and possibility.
