Anna Heymes, the wife of a senior government official, suffers from amnesia and from terrifying hallucinations: she doesn't always recognise her husband's face and sometimes not even her own. With the help of a psychiatrist, she learns that she has had a most complex form of facial surgery and now looks nothing like she did before. From this moment, two questions haunt her: Who did that to her and why?

In Paris's 10th arrondissement - the Turkish district - two police officers are trying to solve the mystery of the torture and subsequent killing of three clandestine Turkish women workers. One of the policemen is a newly graduated inspector, the other a regular of the disrtict, supposed to be retired. As the investigation develops they discover that the "Grey Wolves", a ruthless group of far-right Turkish mafia, might be responsible for these particularly atrocious murders.

As Anna is trying to find out who she was before she became amnesiac, she learns that she used to be closely linked to the Grey Wolves. Now she has no choice but to confront an astonishing and horrible truth.
