Justine and Richard have been together for 15 years. They have three children. Justine is going to leave him. He moves into another appartment, and takes a job abroad. Separation. Two people suspended between the weight of the past and an uncertain future. Both re-discover parts of their past: Richard is reunited with a seventeen year old son and Justine revisits memories of childhood: the father who abandoned her, her first heartbreak, falling in love with Richard. It's nearly Christmas, and they haven't seen each other in a year. Justone and the children still live in the same neighbourhood, in the same apartment to which Richard is returning this evening.
