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.

Bartlet decides he needs a lawyer when Qumar goes after Israel; Josh is disturbed to learn that Stackhouse might not endorse Bartlet; a comment Deborah made years ago comes back to haunt her during a security check.

Leo meets with the Israeli Foreign Minister to enlist Israel's assistance with the Shareef investigation, but is ultimately foiled by the Qumari; the debate about the Ritchie debates rages on until the staff comes up with a brilliant tactic; Josh and Amy argue over whether Stackhouse is siphoning votes from Bartlet; Ritchie tries to bait Bartlet on needle exchange programs; Bartlet is faced with resolving an 11 day standoff with the KSU bombers in Iowa who are holding an injured child; Josh sends Donna undercover to a seminar held by one of Ritchie's advisors in an effort to expose the "fortune cookie candidacy"; Stackhouse comes to a momentous decision about his campaign and provides inspiration for Bartlet.

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.

As the search for Zoey continues, Walken takes a hard line against the kidnappers that could contribute to her death; Danny releases the Shareef story, and the revelation creates a rift that separates Jed from Abbey and Liz; tensions arise between Walken's staff and Bartlet's staff; the Democratic leadership in Congress assails Leo for allowing Jed to step aside; in retaliation for Shareef's death, a movie theater in Turkey is bombed, and eighty people, including American soldiers, are killed.

Bombs drop on Qumar upon Walken's orders; as the hours pass without any word on Zoey's whereabouts, tensions increase within the Bartlet family; Walken and Leo clash after Josh's suspicion that the opposition is using Walken's tenure in the Oval Office to advance their agenda is confirmed; Andy takes the twins home; Leo inflicts a new intern from a prominent political family on an unwilling Josh; Jed's staff is less than thrilled when they learn who will succeed Walken as Speaker of the House; the search for a new Vice President is accelerated; Zoey is rescued.

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