The 4400 is a science fiction television program produced by the USA Network and Sky One. It was created and written by Scott Peters and René Echevarria, starring Joel Gretsch and Jacqueline McKenzie. The 4400 is produced by CBS Paramount Network Television (known as Paramount Network Television during season 2, and Viacom Productions during season 1 until that was folded into Paramount Network Television in 2005), in association with Sky Television for Sky One, Renegade 83, and American Zoetrope for USA Network. The series is filmed in Vancouver, British Columbia, Canada.
In the pilot, what is originally thought to be a comet deposits a group of exactly four thousand, four hundred people at Highland Beach, in the Cascade Range foothills near Mount Rainier, Washington. All of the 4400 had disappeared at various points starting from 1946 in a beam of white light. After their return, none have aged, all are disoriented, and remember nothing between the time of their disappearance and their return.
