1991

December 1991. A recent police academy graduate, Franck Sharko, joins the criminal investigation department in Paris. However, instead of action, he is assigned to the archives and a cold case involving three women who were abducted and stabbed. After years of investigation, the killer is still at large. The breakthrough comes when a terrified man arrives at the police station with a photograph of a woman tied to a bed, her head covered by a bag. An address on the back of the picture leads Sharko into an investigation that will surpass his worst nightmares.
