Achille and Stella have been together since they were 15. Now that they are 30, the two feel like they have rushed through all the stages of life: they have a son, a farm and a mortgage to pay. Stella has never stopped dreaming and is increasingly tired of Achille’s superficial behaviour. So, Stella decides to take a break and visit an old childhood friend in Rome. It is here that she meets Gil, an open-minded chef of African descent with a contagious smile, at a party and lets herself be carried away by a night of passion with him. The next morning, the guilt is devastating and, back home with Achille, she spends a night of love with him. That very night, the unthinkable happens: Stella becomes pregnant. Yes, but by both men. The gynaecologist explains how this is possible at the time of delivery: it is heteroparental fertilisation, an extremely rare phenomenon. In fact, there are only 25 other cases worldwide like Stella’s. Will Stella be able to survive Achille’s judgement, her relatives’ nervous breakdowns and the village’s plethora of gossip, and finally find her way?
