There is a lot of tension and resentment in Romain's and Jeanne's marriage, but their divorce is amicable. They seem to agree on how to raise their daughter, Madeleine - she will live with her mother and spend every other week-end with her father. But Romain is very controlling and manipulative and is poisoning the arrangement. At first, Jeanne seems to cope with being a single parent, but when she has to put up with Romain's tactics she starts to fall apart.
