Q:Build a movie plot around this: Who does John receive a call from? Dr. Daniel Schreber
A:
John Murdoch (Rufus Sewell) wakes in a hotel bathtub, suffering from what seems to be amnesia. As he stumbles into his hotel room, he receives a call from Dr. Daniel Schreber (Kiefer Sutherland), who urges him to flee the hotel from a group of men called The Strangers. During the telephone conversation, John discovers the corpse of a brutalised, ritualistically murdered woman, along with a bloody knife. Murdoch flees the scene, just as the Strangers arrive at the room. Eventually he uncovers his real name, and tracks down his wife Emma (Jennifer Connelly). He is also sought for a series of murders, which he cannot remember, by police inspector Frank Bumstead (William Hurt). Murdoch stays on the move in the city, which experiences perpetual night. He sees people fall comatose at the stroke of midnight, and he is pursued by The Strangers. In the chase, he discovers that he has psychokinetic powers like the Strangers, which he uses to escape from them.Murdoch questions the dark urban environment and discovers through clues and interviews with his family that he was originally from a coastal town called Shell Beach. Attempts at finding a way out of the city to Shell Beach are hindered by lack of reliable information. Meanwhile, the Strangers, disturbed by the presence of a human who retains their powers (which they refer to as tuning) inject one of their men, Mr. Hand (Richard O'Brien) with Murdoch's lost memories, in an attempt to track down Murdoch.Constantly on the run, Murdoch witnesses the Strangers altering the city's landscape and people's identities during the still period at midnight, during which time everyone is unconscious. Murdoch eventually meets Bumstead, who recognizes Murdoch's innocence and has his own questions about the nature of the dark city. They find and confront Dr. Schreber, who explains that the Strangers are endangered alien parasites with a collective consciousness who are experimenting on humans to analyze the nature versus nurture concept of their human hosts in order to survive....
