When Christophe, a rising actor, leaves Jean for his own double—a stand-in meant to replace him on set—Jean spirals into doubt and obsession. Between their apartment, haunted by memories, and the chaos of a film set where the line between artifice and reality blurs, he loses himself in a troubling search for identity. The more he tries to reinvent himself to win Christophe back, the more reality slips away, pulling him into a world where illusions take on a life of their own—and where he himself may become nothing more than a reflection.
