It's possible this is the work of a serial killer. The detectives are pressured to find the killer before he strikes again. Police learn that someone had called and sent unwanted email to Karen Webster. Apparently, she met the mystery emailer in a chat room. Police use email addresses to track down Karen's friends, who also happen to be regulars in the same chat room.
Police locate the others from the chat room.
However, one girl is being stalked and another is attacked. When police think they are protecting all possible victims, the killer catches them off guard. He attacks while the police are conducting a chat room sting. A connection is made between these murders and a series of murders that took place in Seattle two years earlier. Join Detectives Sam Ashburn and Mike Murphy as they enlist the aid of a psychologist and a computer systems expert to untangle this mysterious web.
