A young lieutenant, fresh from school, starts in Paris in a homicide squad. He grew up in Le Havre, where his wife still teaches at school. He misses her and tries to get her to move to Paris too. His boss is a very good police inspector, who just returns to the police after having dropped for personal reasons. She had lost her only son and became an alcoholic. Now she is clean and takes over a new group. Soon they have to investigate the murder of a homeless person. The search for the killer brings big dangers for most of the group, but specially for the lieutenant and his boss.

The film shows some everyday routine of police work and how the officers enjoy themselves after their day is done. There are no big things going on, even the murder case is not very special. It is the personal situation of the two main characters that involves the interest of the audience. Well done, though not really great. 7 out of 10.
