I finally found a movie concept I wanna stick with, this one will probably be released in episodes:
It's about a person who has been hit by a car, and is clinically dead on arrival to the hospital.
He is revived, slowly but surely; But there's a problem - He has severe amnesia, and cannot remember anything about his life prior to the crash. Different people try to tell him different things about his past to influence his actions, everyone is trying to gain control over him.
Tell me what you think of this concept.
