Coup de chance

Two young people's bond leads to marital infidelity and ultimately crime. Fanny and Jean have everything of an ideal couple: fulfilled in their professional life, they live in a magnificent apartment in the beautiful districts of Paris and seem to be in love as on the first day. But when Fanny crosses, by chance, Alain, a former high school friend, she is immediately capsized. They see each other again very quickly and get closer and closer.
