When Louise Morvand returns from a business trip to China she discovers that a crime has been committed in her hometown. A woman has been murdered in the very street where Louise lives with her husband Pierre. Upon initial police investigation it appears that there were no witnesses to the crime,[5] and Louise's neighbours seem to be strangely uninterested in finding the murderer. Haunted by a feeling of guilt, Pierre goes to the police station and admits that he heard screams and saw the attacked woman from the window on the night of the murder. Following his testimony at the police, Pierre is misunderstood by his wife and ostracized and harassed by his neighbours. A full investigation reveals that 38 people actually witnessed the crime, but none of them called police or did anything to help the victim. Journalist Sylvie Loriot is determined to reveal the truth to the public. The police reconstructs the crime with the help of the witnesses, and Louise leaves her husband.
