It's 2008 and Walter Emerson (KEVIN POLLAK), the incumbent President of the United States, is trying to make his way out of Colorado after that state's primary. Unfortunately, a raging snowstorm results in him and his entourage, including Chief of Staff Marshall "Marsh" Thompson (TIMOTHY HUTTON) and National Security Advisor Gayle Redford (SHERYL LEE RALPH), seeking shelter in a greasy spoon diner in Aztec, Colorado.
Having been appointed after the death of the former President, Emerson is faced with criticism about not being an elected leader, but his victory in the primary raises his and his team's spirits. As such, he's happy to "press the flesh" with the few people in the diner, including its owner, Harvey (BADJA DJOLA), and French Canadian waitress, Katie (CLOTILDE COURAU), as well as a local redneck, Ralph (SEAN ASTIN) and a married couple, Lizzie (KATHRYN MORRIS) and Taylor Woods (MICHAEL MANTELL) who are passing time there playing chess.
The happiness quickly ceases, however, when a TV broadcast indicates that Uday Hussein, the current Iraqi dictator and son of Saddam Hussein, has sent his troops pouring into Kuwait, prepared to overrun Saudi Arabia and use various weapons on Israel. While that growing international crisis is bad enough, the U.S. military's conventional forces are stuck in other international hotspots, and the fact that the Iraqi forces also killed several hundred Americans in an U.N. unit only makes matters worse.
Stranded at the diner, Emerson springs into action, contacting his many advisors over secured satellite relay phones. Then, making a bold move and utilizing the network camera crew that's been following his campaign trail, he goes on the air live, addressing everyone around the world. It's during this address that Emerson gives the Iraqi leader an ultimatum - withdraw the troops or face a nuclear strike on Baghdad.
With only ninety or so minutes to spare, Emerson orders the bomber to head for Iraq. From that point on, he must contend not only with that foreign country's reactions to this threat, but also his, his staff's and the similarly stuck civilians' second guessing of his strategy.
