Collier has closed down Arcadia Estates and his home, built a shelter for the 4,400 people, and is preparing to open a "4,400 center" where others can go deep into the 4,400 people and discover the mysteries of the 4,400 themselves.　　The world was so curious about the 4,400 people that rumors of their mysterious abilities spread and public attitudes were divided between those who were tolerant of them and those who were afraid of them. As 4,400 people struggle to restart their "interrupted lives," each will play a key role in the upcoming events... Those events that determine the fate of humanity.
