Kevin runs for his life when he becomes a marked man because of his promicin research; and as Tom and Diana search for him, they discover the depths of his devotion to his work. Also, Shawn meets his idol at the 4400 Center.
The 4400 tells the stories of 4,400 people who disappeared over a period of fifty years and who all reappear at the exact same time without any memory of where they've been and what happened to them. Some of them have been altered and have strange abilities, both good and bad.
The series kicks off with a ball of light sailing toward Earth, but rather than the expected catastrophic event, thousands of people emerge from the ball of light. The returnees have been missing from a few years to several decades and no one has aged a day.
