[Opening narration, season 1
Chester's Mill is a place like any other. At least, it used to be until we were cut off from the rest of the world by a mysterious dome. Invisible, indestructible, and completely inescapable. We're trapped. We don't know where it came from or why it's here, but now that we're all trapped under the dome together, none of our secrets are safe.
