August in Paris' suburbs, seven friends are gathered to spend a week in the city where they grew up. The city is empty and the days pass by under a deep blue sky. Each of them has a reason to be there: some still live there, some come back to see their family, some are searching their childhood, some want to escape boredom or eventually searching for love. They are all bearing the fact that these moments they are sharing are maybe the last ones.

On Christmas Eve, a West suburb of Paris. Stéphane, Joëlle, Xavier and Sonia (25 years old) decide to take a stroll down the big park overhanging the city of their youth, musing on pop music, their work, sex and their disappointed ambitions.

In high summer, Sasha suddenly dies. Her death brings two virtual strangers, her boyfriend Lawrence and sister Zoé, closer together, sharing their grief and the burden of their loss in Berlin, Paris and New York.

One night, three young women, the neon lights of the boulevards, empty streets, a mall, quiet gardens, the tower plaza, the esplanade of the station, a farewell coffee, a camera, a concert, a terrace, then the city waking up, Montparnasse.
