The Man Who Dreamed Upside Down

Paris, second part of the 19th century. Doctor Parent, eminent physician of the Parisian high society, receives an impromptu visit from Mathilde, the young wife of one of his friends. She urges him to leave for Normandy urgently: She is convinced that her cousin Edward is in mortal danger. She takes advantage of the train ride to make him read Edward's diary: the doctor is troubled by the story of a man stalked by an evil presence. Is it of a paranoid delusion or a real intrusion? The rationalism of the doctor Parent is going to be seriously hurt.
