Le Somnambuliste.

Simon, a thirty-year-old sleepwalker in the midst of an existential crisis, keeps waking up at night and sows terror in Westheim, an Alsatian town lost in the heart of the vineyards. Faced with accusations from residents and the police who consider him dangerous, he is convinced that he is the victim of a plot that drives him to commit crimes of which he is unaware.
