A man in his mid-20s, still living at home with his mother and stepfather, puts all his eggs in one basket: the girl who works at his local coffee shop. The problem is, she has a serious boyfriend. As they become closer, the line between friendship and intimacy is blurred, and the situation forces both to examine where they are in their lives.

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.
