One Night

Pierre Morvand (Yvan Attal) wants to be rid of what he heard from his window in Le Havre: a woman stabbed below the building, and the cries for help that nobody answered. He tells his wife Louise (Sophie Quinton), then the police, and the investigation finds 38 neighbors who also watched or listened and never called. Lucas Belvaux is less interested in the killer than in a whole street that stayed behind its curtains.
