François Sentinelle has two lives. By day, he is the most famous cop of Réunion Island, known for his tough methods and flowery shirts, pursuing criminals in his famous yellow defender. But the rest of the time, Sentinelle is also a charming singer.

With the help of her alters, an ex-spy with dissociative identity disorder hatches a plan to get revenge on the one-eyed, the man who tried to kill her. Morgane has many characters who live inside her, and with their help she develops a plan to track down her target: a one-eyed double agent. As each day their identity is alternated, the alters use a Dictaphone to record their days and share the information of their daily investigations. But along the way they are betrayed by one of their own, Louise, who joins forces with two thugs to be freed from this life under control, who agree to help her in exchange for a fortune. The two men manipulate the identities, pretending to be the man they are looking for -the one-eyed. But soon the trap closes on them, and they become the victims of the obsession of this woman with many faces.
