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

SYNOPSIS:
Tom and Diana investigate supermarket employee Carl Morrissey.  But after having gone missing for 18 months, Carl discovers that he somehow now possesses enhanced reflexes and strength. Carl uses these skills to wage a one-man war against crime in his neighborhood.  Doing so, he became a hero not only to himself but to Grace as well. But fighting crime can prove deadly, even for a member of the 4400.

Meanwhile, Richard and Lily have moved in together. As Richard struggles to find work, he must also deal with a pregnant Lily's claims that the baby, still in vitro, is able to communicate its thoughts and feelings to her.

Elsewhere, Shawn and Nikki's attraction to one another continues to intensify in spite of Danny's growing suspicions. 

Diana finds herself growing close to eight-year old pre-cog Maia Rutledge. Concerned about Maia's lab-rat existence in quarantine, she invites the girl to move in with her.
