Elise is a young woman 19 years old who return home after having spent a school year in Spain. She meets again her parents and is surprised not to see her twin brother, Loïc. Her parents explain to her that her brother has left home after a violent quarrel with their father. But, she is astonished not to have received phone calls from him. She suspects that something arrived to her brother, but she has no means to get news from him. Then she decides to stop to eat. Her parents are obliged to send her to an hospital and it's only when she receives post cards from her brother that she stop her hunger strike. But things are not simple and she shall discover later truth about his brother disappearing. The movie is a very dramatic painting both on conflict between parents and child, but also on love that ties twin brother and sister. Acting is very good, specially for Mélanie Laurent and Kad Merad and I consider this movie as a great one.
