In an inner journey to the heart of the human psyche, a character explores the different strata of his personality - the ego, id, superego and self. Guided by a luminous prism, he ventures into the meanders of his mind, where perception becomes blurred, time distorts and the boundary between real and imaginary blurs. A blend of traditional cinema and 3D animation, Le Miroir questions the nature of consciousness and invites us to plunge into the mystery of inner experience.
