Under The Dome, based on Stephen King’s best-selling novel, tells the story of a small town that is suddenly and inexplicably sealed off from the rest of the world by an enormous transparent dome. It’s been two weeks since the dome descended upon the sleepy town of Chester’s Mill, whose inhabitants are still struggling to survive with resources running low as their search for answers to what the barrier is and where it came from continues. The post-apocalyptic conditions intensify while the residents must decide who to rally behind as new faces emerge and Big Jim continues to battle for the town’s trust and allegiance. With survival hanging in the balance, can the residents of Chester’s Mill work together to protect their uncertain future?
Marg joined the cast of Under The Dome for its third season in the summer of 2015. She plays Christine Price, an anthropologist who has somehow been living in Chester’s Mill the entire time and who will be able to provide answers as to why the dome came down over their town.
