The entire Bartlet family tries to gather for an early Christmas dinner at the White House, but inevitable delays occur as the president must deal with an overseas crisis. Ellie is held up at her lab, and five-year-old grandson Gus is having tantrums. In addition, Doug Westin (Jed and Abby's son-in-law) approaches Josh about running for an open congressional seat in his home district. Josh, Leo and the New Hampshire Democratic Party have already chosen a viable local candidate, but Doug persists. Jed, who likes and respects Doug, still thinks it's should be Liz who should run for the open seat.

President Bartet's attack of multiple sclerosis requires hasty reorganization of the summit in China. Unable to endure the long meetings, he becomes frustrated when the Chinese take advantage of his absence to drag their feet over North Korea. Back at the White House, Josh is told by NASA that a large asteroid is on a collision course with earth; staffers are unsure whether to prepare for the end of the world or not. Donna becomes frustrated when Josh continually postpones what she says is an important conversation. With the New Hampshire primary looming and Vinick looking like a formidable opponent, Josh and Leo try to find a Democratic presidential candidate they can believe in.
