Séléna is the police chief of Marseille. Respected and feared by his soldiers, it appears that his only enemy is himself and his 300-pound frame. Tortured by his history and strangled by the expanding straightjacket of his body, he lives alone in a vast, remote house. Only Séléna knows that Elsa murdered her shipowner uncle. Fascinated by the young woman's beauty, he proposes an unusual bargain: in exchange for his quiet, she must dine with him every night for a year.
