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.

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.

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.

Saïd, seventy, has been demoralized by his wife’s illness which has left her hospitalized. He withdraws into solitude and writes poetry to express the infinite love he carries for his beloved.

Alex is a liberated, apparently sturdy yet vulnerable woman in her thirties. She earns her living as a market trader and with building work - she has no trouble matching up to the men. She works on renovating an old dilapidated house, high up and lonely in the mountains of the Ardèche, in the hope that her teenage son Xavier, who was not brought up by her, will move in. The walls she is restoring are like her life, which she wants to build up bit by bit. Because it's clear that she has just lived through some difficult years - in her own defensive words, she says to her son: 'I was unstable.' She is still easily upset and can become angry and aggressive.
