The Divorce

The differences in legalities and cultural mores of French and Americans regarding sex, love, marriage, religion, and family bonds are presented through the interactions of two families related by marriage. American Isabel Walker (Kate Hudson) heads to Paris to visit her half-sister, poet Roxeanne de Persand (Naomi Watts), who is early in the pregnancy of her second child. Isabel arrives to find that Roxy's French husband, Charles-Henri de Persand (Melvil Poupaud), has just left Roxy, the sisters both eventually further learning that it is because he has fallen in love with another woman, who is married. Roxy and Charles-Henri deal with their break-up, which Roxy does not want, but must face the legal consequences of, including determining the ownership of what may be a valuable French painting that has been casually in the Walker family for years, but which Roxy has had in her possession since she got married. Meanwhile, Isabel begins to explore all that France has to offer, which includes concurrently embarking on sexual relationships with two men, including one with Charles-Henri's older maternal uncle, the wealthy and well-appointed Edgar Cosset (Thierry Lhermitte), who is already married and who is using the same playbook on her that he has on countless women before her. As groups and individuals within the two families disagree and argue about certain issues they are facing, it does not necessarily affect other issues and relationships between the two families based on their priorities and those cultural and legal standards.
