EPISODE PREMIERE: July 11, 2004
4400 people, assumed to be dead or missing over the past fifty years, reappear in a ball of light.
When a comet that was supposed to harmlessly fly by the Earth suddenly
changes course, the extinction of mankind seems imminent. Countries
around the world launch nuclear missiles to destroy it before it can
destroy the planet, but surprisingly, the missiles have no affect. The
reason: this is no comet.
The ball of light enters the atmosphere, and just when it looks like humanity is about to go the way of the dinosaur,
the ball slows, hovers, and eventually touches down. Soon after, the light shrinks to an intense point, then explodes
outward in a concussive burst, leaving behind 4400 people, including men, women and children of all ages. All are missing
persons who have been gone anywhere from a few months to 50 years - and none have aged a day beyond when they were last seen.
The 4400 are rounded up, quarantined, and eventually released back to their families. As they begin to try and reconnect
with their "life interrupted," not all is well: soon after their release, some of the returnees begin to experience
unexplainable, and for some, uncontrollable new abilities. It's up to Tom Bishop and Diana Skouris, two Homeland Security
agents, to unravel the mystery behind the 4400.
