The boundaries between military discipline and human desire are tested on a U.S. Army base that houses an elite unit of helicopter pilots trained to perform clandestine international and domestic missions. The drama unfolds in the present as well as in flashbacks to a failed mission involving one of the first female pilots in the unit, ultimately uncovering layers of personal and government/military secrets and leading to a season-long plan to rescue a group of MIA soldiers.

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.
