Recalling such prior successes as The Big Chill, Peter's Friends, and Return of the Secaucus 7, director Dani?le Thompson's seriocomedy A Change of Plans follows a group of four French couples who converge in an apartment over the course of one lengthy summer's eve and spend the time chatting about life, personal goals, relationships, and sex. The said event unfurls during the perennial "F?te de la Musique" in the City of Lights. Attendees include the shark-like divorce attorney who owns the apartment, ML (Karin Viard), and her out-of-work husband, Piotr (Dany Boon); slick, unctuous attorney Lucas (Christopher Thompson) and his slightly stuck-up homemaker wife, Sarah (Emmanuelle Seigner); gynecologist Melanie (Marina Fois) and her oncologist husband, Alain (Patrick Bruel); and ML's sister, Juliette (Marina Hands), and her much older boyfriend, Erwann (Patrick Chesnais). As the night unfurls, it becomes readily apparent that none of the partners are happy and that virtually all have cheated or are planning on cheating on each other, which turns the film into an extended meditation on dissatisfaction and infidelity among the Parisian upper crust.
