Every cop has a case that haunts them and takes over their whole life.

In 2002, the biggest case of paedophilia in France breaks out in Angers. For more than two years, Fabienne Lopeo of the juvenile brigade leads the investigation. It's a case that will affect her life deeply.

Episode 2, The Angers Paedophile Network Case

The murder of 16-year-old schoolgirl Christelle Maillery, committed at Le Creusot in 1986, is now resolved...30 years after her death. The fact that the culprit is now under lock and key owes much to the obstinacy and the intelligence of one man, Raphael Nedilko, a detective who is asked in 2009, 23 years after the event, to re-open the investigation.

Episode 3, A French Cold Case

Eric Trunel, then commander at the legendary 36 Quai des Orfevres, plunges ten years into the past to revisit a case that marked him, one he will never forget.
