A teenage girl steps over the line into adulthood during a summer abroad in this drama from writer and director Heitor Dhalia. Mathias (Vincent Cassel) is a successful French novelist who packs up his family, including wife Clarice (Debora Bloch) and fourteen-year-old daughter Filipa (Laura Neiva), for a few months of vacation at a beachfront house in Brazil. While their surroundings are idyllic, not everyone is happy, and Filipa is aware of the obvious tension between her bickering parents. The contentious relationship between Mathias and Clarice explodes when she learns that he's been unfaithful with the younger and sexier Angela (Camilla Belle). Filipa, who is all too aware of her growing attraction to the opposite sex, is at once disturbed and excited when she spies Mathias and Angela making love, and she decides to act on her desires for a handsome neighbor in his early twenties. A deriva (aka Adrift) was an official selection at the 2009 Cannes Film Festival.
