Tony and Justin, and some guy from Lockheed Martin, are competing for the last weapons contract of the W. Bush presidency. Dick Cheney makes them prove their respective American manlinesses on a Wyoming hunting trip. Because he's an asshole. And because Tony pissed him off during the first Gulf War, and he's holding a grudge.
It's 2007, and Iron Man is not yet a twinkle in Tony's eye. He and Justin will end up boning in an unpleasant and regrettable way that Justin will forever remember and Tony will try to forget.
