It's Big Block of Cheese Day again. Toby meets with World Trade Organization protesters, and CJ meets with a group of cartographers who want the standards for maps changed to be a more accurate reflection of geographical and political reality. Donna asks Sam to look into granting a pardon for a friend's deceased grandfather. Bartlet is having problems selecting a site for his Presidential library.

Leo fears the worst when he testifies in the congressional investigation into Bartlet's lack of public disclosure about his illness.

When Bartlet learns that Zoey's kidnapping is the work of Qumari terrorists, he invokes the 25th amendment to diminish their leverage and eliminate any conflict of interest; since there's no Vice President, the power of the Presidency passes to Bartlet's chief political rival and the most powerful Republican in the country, the Speaker of the House, who immediately takes a very hard line; now that twins Huck and Molly have arrived, Toby wonders if he's capable of loving them enough.

A documentary camera crew follows C.J. around for a not-so-typical day in the White House.
