Casse-tête chinois

Ten years have passed, and the once happy lovers, Xavier Rousseau (Romain Duris) and Wendy (Kelly Reilly), have split. When she moves with their two children to New York City, he also moves to there to be near the children. Wendy now lives with John (Peter Hermann (actor)) in a luxury apartment overlooking Central Park. Xavier initially stays with Isabelle (Cécile de France) and Ju (Sandrine Holt), a lesbian couple whose child he fathered, but he soon finds his own apartment above a Chinese bakery where he works on a new novel assisted by brief visions of Arthur Schopenhauer and Georg Wilhelm Friedrich Hegel.
