Bertolucci directs this erotic drama based on a novel by Gilbert Adair. Set against the backdrop of a politically-turbulent Paris in 1968, the film tells the story of Matthew (Michael Pitt), an American student abroad, who befriends twin brother and sister Theo (Louis Garrel) and Isabelle (Eva Green) at a political demonstration. The three share a passion for cinema, and quickly become friends. When the twins' parents (Robin Renucci and Anna Chancellor) leave the city for the summer, the twins invite Matthew to live with them in their sumptuous Bohemian flat. As the revolution rages outside in the streets, the three embark on an intense, insular journey that will change Matthew's life forever.
