Tom and Diana are sent out to investigate a homicide that resembles the MO of a serial killer who was never caught nor heard of for 21 years. The first suspect is Oliver Knox, a member of the 4400. However, Knox has an alibi for the night of the murder and another man confesses to all the crimes. Tom and Diana suspect that Knox is luring people to kill for him and try to lay a trap on him. Meanwhile, people begin to turn hostile toward the 4400, and Jordan Collier decides to organize his fellow returnees. But Richard feels uneasy about Collier's interest in them.
