A series of murders are investigated in Paris' Turkish community. In a steel-gray Paris, Anna is losing her memory. She can identify the face of Abe Lincoln but not a photo of her own husband of eight years, Laurent. He and neurologist Dr. Ackerman urge her to have a biopsy, but she refuses. Instead, she picks shrink Mathilde out of the phonebook in search of a solution to her condition. Elsewhere, idealistic young cop Capt. Paul Nerteaux is fishing a third mutilated Turkish woman's body out of the Paris sewers. Paul enlists the help of Schiffer, a disgraced cop who patroled Paris' Little Turkey district for 20 years. Nobody on the force cares if a few illegal Turkish seamstresses have been tortured and carved up, but Paul's mom was murdered when he was a boy and since he can't catch her killer, he's determined to catch this one. Neither Anna or Paul know what lies ahead for them.
