Josh speaks to a psychiatrist about the events of the last three weeks: Toby hired musicians for the foyer, an Air Force pilot disobeyed orders, Yo-Yo Ma performed at the White House, and Josh managed to cut his hand quite badly.

Toby wants to use a bipartisan breakfast to discuss real issues instead of making it a staged event; Sam floats the idea of moving the press room across the street; Leo wants Josh to apologize to a columnist on his behalf; Leo and Toby realize they need to start thinking about reelection.

Sam meticulously prepares a speech for the President to give to the environmental lobby, but Toby wants to sneak in some criticism of their failure to condemn environmental terrorism. Leo tries to convince the President to support his pet project - a missile defense shield - despite its continued failure to produce results, and the fact that it likely contravenes an anti-ballistic missile treaty. Several countries including Great Britain have sent new ambassadors to Washington to be recognized by the White House. C.J. travels to New York on a delicate mission to ask for a political favor from a comedian.

President Bartlet is fighting a war on two fronts as he tries to rescue hostages in Colombia and deal with explaining to his wife why he's breaking his word to her by running for a 2nd term.

Comments made by Surgeon General Dr. Millicent Griffith concerning the medical effects of marijuana appear to reverse the President's stance on legalizing the drug.

On this year's "Big Block of Cheese Day", a college friend of Donna's asks Sam to help her get her late grandfather, accused of being a Communist spy inside the U.S. government, a presidential pardon; dealing with the recent revelation that his father had been having an affair for the past 27 years, Sam faces off with an F.B.I. agent, and later with Nancy McNally, over the pardon. Elsewhere, a group of cartographers completely re-educates C.J. on her perception of the globe, and one-time protester Toby, with the help of a straight-talking female security guard, speaks for the w.h. at a rally to protest against U.S. participation in the WTO and various free trade agreements.

Josh finalizes a $6B health care plan that has strong support from both parties in both houses and appears to be a slam dunk for passage, but 78-year-old Senator Howard Stackhouse pulls a last-minute surprise--he wants money added for autism research or he'll filibuster. Thinking it's just a bluff, Josh blows off the senator, who then filibusters for more than eight hours while the WW staff waits desperately to begin their weekend with the episode unfolding as staffers write e-mails to their family members describing the evening's action. Elsewhere, Sam tries to eliminate various costly government documents, for which he's taken to task by a very young intern.

Following the Vice-President's remarks to him, Toby realizes the truth behind the President's illness: multiple sclerosis. Toby, Leo, and Bartlet discuss the possible political implications of this if it goes public including possible jail time for the 17 people who now know about the illness. Meanwhile Sam, Josh, Donna and the rest of the staff, unaware of the illness, struggle with a speech the President is to give at the White House Correspondents Dinner.

White House Counsel Oliver Babbish interviews CJ once she learns of the President's condition. The First Lady learns she may be legally vulnerable. Donna frets over news of a falling satellite.

With hypothetical polling numbers showing them it will be political suicide, staffers prepare to announce the President's condition. As they do, a military crisis flares up in Haiti and Josh faces off against two senators who are against the Government's tobacco industry suit. But as badly as the day seems to be going, a tragedy will come from a car wreck at 18th and Potomac that will affect everything.

As the Haitian army continues their seizure of the American embassy there, Bartlet and the staff prepare for the announcement that Bartlet has M.S. and the President must decide whether or he will seek re-election. As the funeral for Mrs. Landingham takes place and the announcement draws nearer, Bartlet thinks back to his past in search of the answer to the question everyone is asking: Will he seek re-election?

The West Wing goes under lock down as a suspected terrorist is found to be working at the White House. Stuck with a group of high school students who were visiting the White House, the staffers, President Bartlet, and the First Lady all debate the issues regarding terrorism. Meanwhile, Leo sits in on the questioning of the terrorist suspect and learns a lesson about our perceptions of terrorists.

With the staff all bickering with one another in Manchester, especially adversarial speech writers Toby and Doug, who angrily disagree about whether Bartlet should make a public apology for lying about his MS, and with the president sniping at everyone, the second-term announcement speech is locked. Abby ultimately forgives the president for deciding to run again without discussing it with her, and he ultimately apologizes to the staff in private for keeping his condition from them, which they expect will soon lead to a whole slew of grand jury subpoenas.

Special prosecutor Clem Rollins announces the grand jury subpoenas in the case of president's failure to disclose his MS to the public, and the list includes pretty much every West Wing staffer and Bartlet family member; Sam and Connie meet with an important Latino activist from Calif. who is considering supporting a primary challenger to Bartlet; C.J. convinces everyone that the special prosecutor is too reasonable, and that the W.H. needs a "better enemy" in the investigation, prompting the staff to provoke a Congressional inquiry.

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.

On the day before Thanksgiving, CJ has to deal with two Stockbridge-Munsee Indians who won't leave the lobby until they get an answer on an application their tribe submitted 15 years ago. Josh tries to arrange the extradition of an underage boy whose parents sent him to Italy after he killed his teacher. The President learns why Abby wants to have Thanksgiving at Camp David this year, and places an anonymous call to the Butterball Hotline.

CJ cannot control her outrage when the US agrees to an arms sale to Qumar, a country that brutally abuses women. Josh meets with Amy Gardner, a leading women's group lobbyist. The content of a Smithsonian exhibit draws protest from a veteran's group. Leo and the President discuss options when the possibility of a Mad Cow infection strikes the US beef industry.

In an episode dotted with flashbacks, Leo and his attorney Jordon Kendall (Joanna Gleason) face a Congressional inquiry into whether the president lied to the American people regarding his MS, but this particular day of hearings concerns itself more with Abby and her secretly medicating Jed, and later with Leo's having fallen off the wagon during the campaign (a politically motivated Republican rep on the committee witnessed Leo drunk in his room three days before the nomination); we see the meeting in which Leo talked N.H. Governor Bartlet into running for president, introducing his idea, "Bartlet for America", on a cocktail napkin, which the president later frames and returns to Leo as a gift in thanks for all he's done for the president over the years; Cliff Calley, Donna's boyfriend and special counsel to the judicial oversight committee, asks the committee chair to halt the inquiry before the rep can compel Leo to admit his personal transgression; Leo asks Jordon to Xmas Eve dinner.

In a private, late-night meeting, Cliff Calley informs Leo and Jordon he has negotiated a settlement in the Congressional witch hunt over Bartlet's MS: Bartlet can accept a joint congressional censure (House Concurrent Resolution 172, or H.Con. 172); Leo initially refuses to bring it to the president, insisting it will devastate the president and affect him for the rest of his life, but he does mull it over, and consults with Josh and repeatedly with Jordon about it; Josh begins his romantic pursuit of women's issues advocate Amy Gardner, but flubs it a couple of times while she continues dating other men.

On the night of the State of the Union, Sam has to explain the process of writing the speech and grading reaction to it to a magazine reporter (Traylor Howard) throughout the evening; C.J. arranged the coverage aware that the reporter, Lisa Sherbourn, is Sam's ex-fiancée; flashing back to the speechwriting process, we see the president dining with several of Abbey's medical colleagues, and they ponder the future of cancer research, motivating Bartlet to ask that a section be added to the SOTU in which he calls for U.S. scientists to find a cancer cure by 2012; the staff, convinced that the Congressional censure is weighing heavily on the president, tries to talk him out of this bold but risky proposal.

Toby is concerned when President Bartlett forgoes an opportunity to speak out in favor of affirmative action during the Iowa caucuses and confronts the President on the real reasons underlying his Dr. Jekyl & Uncle Fluffy personality shifts. Meanwhile Josh makes plans for a vacation with Amy and then must cancel them.

Josh covertly brings a psychiatrist to the white house to meet with the President who has been unable to sleep for five days.

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.

A lavish W.H. party for Abbey's birthday the night before a N.H. medical board begins hearings on whether to suspend her license over her secret treatment of her husband's MS. Abbey returns to the residence with C.J. and Amy Gardener to get blitzed on wine and discuss her concerns about her medical career. Donna is restricted from joining the party because a decades-old cartography error puts her birthplace in Canada. Toby and U.K. Ambassador Lord John Marbury (Roger Rees) go to a nearby bar to share a bottle of very rare Scotch and to discuss a planned W.H. visit by an IRA political activist, which culminates in Marbury surprising Toby with his progressive vision. Later, Donna joins the women in the residence and makes an off-the-cuff remark that causes Abbey to rethink her stance on the issue of her license.

Poet laureate Tabitha Fortis visits D.C. to attend a White House dinner in her honor, and Toby develops a bit of a crush on her, but he also must admonish the somewhat flighty beauty against publicly criticizing the president for his refusal to sign an international anti-land mine treaty; Donna discovers a website devoted to Josh, and he soon becomes sucked into the online chat about his activities and ego; speaking via remote to a local morning show in Philadelphia and unaware that the mike is on, Bartlet makes a stray comment impugning opponent Robert Richie's intelligence, for which the staff, particularly C.J., takes a lot of heat from Richie campaign and the press.

On a typical night in the west wing, Sam returns from a hockey game and Josh asks him to meet with V.P. Hoynes about saving an education bill. Back at the W.H., Josh, Toby, Leo, C.J., Larry and Ed all meet about the prospect of replacing Hoynes on the ticket in the next campaign. Bartlet helps Charlie do his federal taxes, and while both think Charlie should expect a refund, thanks to last year's so-called economic stimulus, he instead owes money to the IRS. A security emergency occurs when two trucks, one stolen and containing nuclear waste, crash in a tunnel in Idaho, threatening to explode and wipe out a nearby town. Donna asks Josh to ask the president for a special proclamation recognizing her favorite h.s. teacher. Bartlet can't oblige, but he comes up with a very uplifting consolation for Donna to let her teacher know how much she appreciated her. Episode title refers to James Bond's preference for "shaken, not stirred," which Bartlet insists results in a weak martini; this ties into Hoynes and Leo making the president aware that Hoynes is a recovering alcoholic, just as the w.w. staff is considering bumping him.

A meeting with the new Russian president becomes politically dangerous when surveillance photos show Russia building a nuclear reactor in Iran. C.J. is assigned Secret Service protection after receiving death threats.

Bartlet and Leo debate on how to deal with the impending visit of the Qumari Defense Minister, whom U.S. intelligence officers have conclusively linked to terrorists. Sam dismisses an ingenious idea to trap Republican presidential opponent Robert Ritchie in an unsavory position over the Everglades, but comes around after talking to Toby. C.J. begins to develop a relationship with Secret Service agent assigned to her, Simon Donovan. Josh and Amy are locked into a battle over a welfare reform bill, which could end their relationship.

Bartlet, Leo, Sam, Toby, and C.J. travel to New York City for a Catholic fund raiser at a long Broadway play called "The War of the Roses". Josh steps up his efforts to beat his girlfriend, Amy, in their struggle over the welfare reform bill, which leads to her forced resignation. C.J. and Secret Service agent Simon Donavon have grown closer, but a tragic event cuts short their relationship. At the play, Bartlet comes face to face with Republican Presidential candidate Rob Ritchie and faces the decision of whether or not to assassinate the Qumari Defense Minister.
