Le combat dans l'île

Clément, a wealthy French industrialist's son, is a violent right-wing extremist who belongs to a secret militant group. His wife Anne, a former German actress, knows about his extreme views and has found disturbing evidence of his willingness to use violence. Despite his poor treatment of her, Anne stays in the marriage. After Clément and a colleague assassinate a Communist figure, they hide out at Paul's country home, where Clément's childhood friend is a democrat and pacifist. When Clément leaves to pursue a mission, Anne reconnects with her old life in theater and starts a relationship with Paul. However, Clément's return causes tension and conflict.
