The third and final season of this sci-fi drama (based on Stephen King's novel of the same name) begins where Season 2 ended, with Barbie (Mike Vogel) and the surviving townspeople following Melanie (Grace Victoria Cox) into the white light. However, what they thought was an escape route is not at all what it seems. Inside the Dome, Big Jim (Dean Norris), Junior (Alexander Koch) and Julia (Rachelle Lefevre) continue their conflicts while FEMA brings in therapist Christine Price (Marg Helgenberger) to help the people of Chester's Mill. But, Christine has her own agenda with deadly consequences, causing the townspeople to join forces with surprising allies.
