Claire Denis's drama is set in the Parisian suburbs where, in an apartment block, train driver and single father Lionel and his student daughter Josephine share a flat and perhaps more. Upstairs lives Noe, for whom Josephine has a thing, while, along the corridor, taxi driver Gabrielle has carried a torch for Lionel for years. But changes are coming into their lives, threatening to pull at the ties that bind them all.
