In the dead of night a helpless female student is stabbed to death outside her apartment building in the port city of Le Havre. However as the police begin a thorough investigation the poor woman's neighbours and the silent complex's thirty-eight tenants claim to have seen--and above all heard--nothing. Under those suffocating circumstances the devastated maritime pilot and ideal suspect Pierre summons up the courage to break the silence as his wife Louise and the determined journalist Sylvie stand powerless before the thick mystery and the burden of choice. Now a gruesome murder one common secret and a pressing "why" demand an answer as 38 witnesses chose to hush up. What will it take to unearth the truth?
