One parting married couple, plus two guys and two gals, interact during a Thanksgiving weekend at a roomy home in the Colorado Rockies.

Diane and Greg Halstead were once happily married, even deciding to try and have a baby in later years, despite the fact that she had already suffered two miscarriages. She has no luck in becoming pregnant and this leads to an estrangement from her husband. On his latest flight, Greg, a professional pilot, finds out about a bomb threat. The person carrying the bomb supposedly wants to kill another passenger, a politician with an outspoken opinion on abortion. Unknown to the killer, however, the politician has already left the plane because it had an hour and a half delay. Greg decides to make an emergency landing in Dayton, Ohio, but during the heavy weather, the plane crashes, killing almost everyone on board.
