This amazing British teleplay concerns a doctor who returns home from the hospital following a car accident, only to be told he's not who he is. Another doctor, with the same name, is living with his wife. He is told that he is suffering from a mental disorder. Has he really lost his mind or is there something sinister afoot? The ending of this film is a total shocker you won't see coming. A great film, with Ainley giving a superb performance as the tortured doctor who is lost in a web of conspiracy.
