După ce Homer poluează accidental sursa de apă a orașului, Springfield este închis într-o cupolă gigantică de către EPA, iar familia Simpson este declarată fugară.

A small town is suddenly and inexplicably sealed off from the rest of the world by an enormous transparent dome. While military forces, the government and the media positioned outside of this surrounding barrier attempt to break it down, a small group of people inside attempt to figure out what the dome is, where it came from, and when (and if) it will go away.
