Six years after resigning from the Paris police force and giving up the hunt for a serial killer, Rebecca is back at work. While investigating a series of brutal murders that all bear the same signature, she becomes convinced that the killer has resurfaced. Obsessed with the case, cheated on by her husband, and hampered by both depression and crippling blackouts, she throws herself into her job to avoid collapsing. Only Rebecca's efforts to track down the killer only bring her demons to the surface.
