Eight years after she left him for his best friend, journalist Abel (Louis Garrel, The Dreamers) gets back together with his recently widowed old flame Marianne (Laetitia Casta, Arbitrage). It seems to be a beautiful new beginning, but soon the hapless Abel finds himself embroiled in all sorts of drama: the come-ons of a wily jeune femme (Lily-Rose Depp), the machinations of Marianne's morbid young son (Joseph Engel), and some unsavory questions about what exactly happened to his girlfriend's first husband.
