While the W.H. is hosting a gala dinner for Nobel Prize winners, Leo and the president learn of a suicide bomb in an Israeli cafe that took the lives of two American students in Tel Aviv for a soccer match, and the staff attempts to manage the president's first veto, of a House bill eliminating the estate tax, and the threat of an override the same night. Sam and Toby first try to sway a contentious Dem. From Tennessee who wants a whole list of farming and ranching concessions in exchange for his vote and three proxies; after a pep talk from Leo, they devise a substitute plan that may prove even more effective, if it works. Josh takes the governor of Indiana into a private meeting to determine if the man plans to challenge Bartlet in Democratic primary. C.J. takes heat from a smarmy Dallas entertainment reporter who is in town for the Nobel dinner but winds up having to cover the veto and override vote, but after the reporter embarrasses her during a live stand-up, C.J. one ups the woman in front of the press corps. Later, Sam, Toby and Josh try to help the president decide what to say to the parents of the two murdered students.

When the military loses contact with a submarine in hostile waters, the President must choose between risking the lives of the crew and provoking North Korea. CJ relishes the Majority Leader's flubbing of an interview. Babbish informs Abby that she is the weak link in the President's legal defense.

A small town in N.H. is the site of the first presidential primary vote, and the results from Hartsfield's Landing, announced at 12:07 a.m., will dominate the news all day until the final tally. Josh wants favorable press for the president, prompting him to ask Donna to persuade a local couple she knows to reconsider their vote. Elsewhere, Bartlet has just returned from India with a collection of antique chess sets he gives as gifts to the staff. He plays Toby while they discuss their recent blow-up, Bartlet's insomnia and Toby's fervent belief that the president's enormous intellectual gravitas is an asset, not a liability, to the campaign. He also plays Sam as they discuss a critical detente standoff between China and Taiwan. And Charlie and C.J. stand off in a series of pranks over a missing copy of the president's private schedule.

Sequestered in North Carolina to prepare for the one and only debate between Bartlet and opponent Robert Richie, the staff and several consultants (incl. Andrea Wyatt and Joey Lucas) flash back to the days just before and after the president's first inauguration, which were marked by an ill-advised choice for attorney general and ongoing concerns about fertility for then-married Toby and Andrea. In the present, Sam plays Richie in mock debates and raises Bartlet's ire, while Leo and the joint chiefs try to convince the president not to treat increasingly aggressive Qu'mar, whose defense minister Bartlet ordered assassinated (late last season), with kid gloves, and the staff keeps pestering Toby about his on-again, off-again relationship with Andrea, until he makes a startling revelation.

Zoey Barlet has been held for over a day. An international crisis looms that could have serious repercussions for the administration, let alone the hostage.
