The 4400 (2004 ​ - 2007)

The 4400 explores the travails of the 4400 people who all at once returned in a ball of light to Earth; though the returnees had not aged physically, many of them reappeared with dramatic abilities ranging from enhanced reflexes to precognition. NTAC (National Threat Assessment Command) is the government agency responsible for keeping track of the returnees and investigating all things related to the 4400.
