Louis Trebor lives alone with his dogs in a forest close to the French-Swiss border, until the need for a heart transplant and the search for a long-lost son compel him to set off on a long journey. Inspired by a philosophical essay by Jean-Luc Nancy, L’intrus follows this journey that weaves together alpine tundra, the neon lights of South Korea and the tropics of Tahiti, with the hallucinations, memories and dreams of an old and lonely man. A visually enigmatic and immersive film.
