This is less about the crime, then the day to day minutiae of police work, in particular the growing relationship between an eager young lieutenant, and his tough, ex-alcoholic boss – Nathalie Baye, in an excellent, uncharacteristically dark performance. There's no romance between the two, just an evolving connection.

In the meantime, the lieutenant's home life is a mess – his wife is understandably angry because he requested his Paris posting, far from their home and her work, without asking her.

This sad, low key, almost documentary like film, without music or fancy shots, is an insightful look into the people who face crime every day. Dense enough that I'd gladly re-see it.
