From French co-directors Robin Bersot, Camille Dellerie, Mickaël Larue and Thomas Rodriguez, Solus (as the film is called) is their graduation film (graduation from ESMA - Ecole Supérieure des Métiers Artistiques).
Carl is a man in his fifties, who’s trying to lead a normal life in an unusual situation with his friend Eddy. One day, while he’s looking for food, he finds Sam, unconscious. Carl brings him back home. When Sam wakes up, he will question Carl’s way of life. The latter is going to understand his meeting is maybe not due to chance.
