A meeting with a patient suffering from amnesia leads psychiatrist Mathias Freire to a horrifying discovery: he has the same “passenger without luggage” syndrome. Time and again he loses his memory and, from shards of the past, creates a new identity for himself. To recover his true self, he will have to pass through all his previous incarnations. Freire is pursued by mysterious killers in black, hunted by the police, who are convinced that he is the serial maniac behind gruesome murders imitating ancient Greek myths. And he himself is not even sure of his own innocence… How can he escape this labyrinth? Perhaps police lieutenant Anaïs Châtelet, for whom he is the prime suspect, will grant him a guiding thread?
