4400 people, assumed to be dead or missing over the past sixty years, reappear with no memories of where they were taken.

SYNOPSIS:
A homicide in rural Washington bears all the hallmarks of the "Friday Harbor Killer," a serial murderer who was active 25 years earlier but was never apprehended. Tom and Diana are dispatched to investigate a possible connection between the murder and Oliver Knox, a member of the 4400 who recently resurfaced in the community. Knox has an airtight alibi for the night of the murder, and when another man confesses to all of the murders, the case seems to be solved. But the killings continue, with another person coming forward and confessing to all the crimes. Forced to contend with the possibility that Knox is somehow convincing his neighbors to commit murder on his behalf, Tom and Diana lay a trap that they hope will prove Knox guilty in the killings.

Aas public sentiment toward the 4400 begins to turn hostile, millionaire Jordan Collier seeks to organize his fellow returnees. After Shawn, Richard, and Lily attend a meeting hosted by Collier, they all find themselves involved with this charismatic leader. However, Collier's intense interest in Lily makes Richard uncomfortable.

Tom receives news that Kyle's condition has begun to deteriorate.  He has been forced to confront the possibility that his son may never wake up from his coma. But Shawn's conversations with Collier have convinced him to explore his abilities, and when Shawn learns that Kyle might be dying, he visits the hospital. Shawn touches his cousin and is able to rouse Kyle from his comatose state.
