Daedalus

Guilty of twenty-seven homicides, Claude suffers from a pathology called “multiple personality disorder”. Seven personalities compete for control of his body.
To try to pierce the terrible secret of this multi-faceted serial killer, two men will have to dive into the maze of his inner world: Matthias, the cop who arrested him, and Dr. Brennac, in charge of his psychiatric assessment.
Little by little, the two men put together the puzzle of a terrifying past. But he who goes down into a labyrinth takes the risk of not coming out.
