An invisible and mysterious force field descends upon the small town of Chester's Mill, Maine, USA, trapping residents inside, cut off from the rest of civilization. The trapped townspeople must discover the secrets and purpose of the "dome" or "sphere" and its origins, while coming to learn more than they ever knew about each other and animals too.

Under the Dome is the story of a small town that is suddenly and inexplicably sealed off from the rest of the world by an enormous transparent dome. The town's inhabitants must deal with surviving the post-apocalyptic conditions while searching for answers about the dome, where it came from and if and when it will go away.—ahmetkozan
