The story tells that in the past hundred years, many people have been abducted by aliens. On a day in July 2004, the US National Security Agency discovered a comet flying towards Earth at high speed, endangering the safety of Earthlings. All countries around the world, including China, launched missiles to destroy the comet. However, it had no effect. Eventually, the comet landed by the lake shown in the picture above. After a mist dissipated, 4400 people from different eras who were TAKEN appeared by the lake, and they all remained intact as they were when they were TAKEN in their respective times. Ultimately, when these 4400 people re-entered society, they found that they possessed extraordinary abilities beyond those of ordinary people. Where did these people go? And how did they return? Why do they have special powers? Why are there exactly 4400 people? What changes will they bring to Earth eventually? Or is this an alien experiment? Or a rescue mission from the future? All questions lie within the series... The American cable network original series "The 4400" was filmed using two Viper cameras, according to the United States America Network (USA Net).
