Blood On The Docks(2011)

Original title: Deux flics sur les docks

Le Havre, France. The city’s at war as local mobsters and petty gangsters fight over territory, while the police do their best to put an end to the drug trafficking that holds sway over town. Set on a backdrop of social misery, the cases followed by dutiful Inspector Faraday and Paul Winckler, his former partner with completely opposite methods, combine gripping realism and riveting investigations.
