The Overeater 2003 on netflix

Séléna is chief of the Marseille police. Respected and feared by his men, his sole enemy seems to be himself, along with his 300 pounds. Strangled by the bursting straight-jacket of his body, tortured by his past, he leads a solitary life in a large isolated house. Séléna is the only person who knows that Elsa was guilty of the murder of her uncle, a wealthy shipowner. Fascinated by the young woman’s beauty, he offers her a strange deal: in exchange for his silence, he demands that she dines with him every night for a year.
