Rémi is a man trapped in a deteriorating marriage. When his wife is unexpectedly killed in a car accident, Rémi is left with his stepdaughter, Marion, who chooses to stay with him rather than live with her birth father. After the initial shock passes, Rémi is caught off-guard when Marion begins expressing her attraction to him. Initially repulsed, Marion's mature beauty wears him down as he finally caves to her seductions.
