Police investigating the murder of a middle-aged office worker discover e-mail correspondence on the victim's computer that indicates he had been a regular participant in an Internet chat room, as the "father" in a fantasy "family." Meanwhile, a female detective is assigned to protect the dead man's real-life daughter who complains of being stalked. As the real daughter confronts her father's alternate life, we are pulled into a psychological drama that pits reality and illusion against each other in astonishing ways.
