Synopsis:
A year after the revelation of the beach incident - 4400 people were taken by people from the future and sent back, the world has changed greatly. After a tense period of medical observation, Tom returned to the National Technical Assistance Center, where due to limited capabilities, he was assigned to clerical work. He eventually protected his son from a similar government study and is excited about the prospect of resuming a normal life. Professionally, he also looks forward to working again with Diana and getting back into the field. Diana, after a series of incompetent partners, finally found a way to destroy the documents to get Tom back on the job, during which she also formally adopted Maia.
Meanwhile, Richard, Lily, and their child - a six-month-old, extraordinary child, still live in a mountain cabin far away from Jordan Collier, leading a simple life. Collier has already shut down Arcadia Estates and his residence, setting up shelters for these 4400 people, while preparing to open a "4400 People Center", where others can delve deeper into these 4400 individuals and uncover their secrets themselves. After Collier experienced an adverse reaction upon touching Lily's abdomen, Shawn healed him, after which they developed a close father-son relationship. Collier became Shawn's guardian and used him to heal the center's key patrons.
