The Black Box (2005)
While driving in a winding narrow road, Arthur Seligman has an accident and capsizes with his car and awakes from a short coma in a hospital in Cherbourg. With amnesia and without recalling why he left Paris, Arthur is informed by the nurse Isabelle Kruger that he had spoken lots of senseless sentences and she gives her notes to him. Arthur reads the disjointed sentences and many images flash in his brain while he tries to find his missing brother, using drugs and psychiatric treatment in his investigation. Suddenly, his reality changes to another one, and Arthur discloses innermost secrets hidden in his mind since his childhood and finds the truth about his brother and himself.
