In a welfare housing block in Malakoff a young volunteer named Camille gives one-to-one classes to Brayan, a 5 year old boy who doesn't talk.

A young mother and her daughter live in an out-of-season seaside resort void of tourists. One lives by night, working in a hotel, and the other by day. They never cross paths and their only link that maintains any sense of common life is a walkietalkie. 

Kicked out roughly by her boyfriend, Olga, exhausted, takes shelter in the gritty flat of her son and his girlfriend. She finds herself trapped in her own torpor, infected by the intimacy of the young couple.
