All four series of the acclaimed French police drama starring Grégory Fitoussi and Caroline Proust. In the first series, the discovery of a young woman's badly-beaten body on a rubbish tip in Paris sets in motion a police investigation that unravels a trail of corruption leading from the dark worlds of prostitution and drugs to the halls of government, business and the judiciary itself. In the second series, public prosecutor Pierre Clement (Fitoussi) once again joins forces with Police Captain Laure Berthaud (Proust) and crusading judge Francois Roban (Philippe Duclos) to infiltrate Paris's underworld of organised crime, international drugs trafficking and arms dealing. During the third series, the emergence of a brutal serial killer offers Berthaud the chance to restore her reputation, but will her very determination to track down the killer lead her over the edge? In the fourth series, lawyer Joséphine Karlsson (Audrey Fleurot) risks all by attempting to defend the rights of a group of unwelcome immigrants. Meanwhile, Berthaud finds herself in the thick of the action when she is seconded to an anti-gang unit shadowing the activities of dissident students engaged in bomb-making.
