After being offered "a proportional response" to the Syrian military's downing of a U.S. military plane on a medical mission (and carrying his newly named personal physician), the president demands an option that will have greater impact. Leo gradually must talk him down, while Bartlet snipes at everyone, including Abby. The president ultimately agrees to the initial option, but is not happy about it. Charlie Young is introduced as an applicant for a messenger job whom Josh decides to hire as President Bartlet's personal aide.

When India sends troops into Kashmir, President Bartlett calls for a British former ambassador to India to help out - over Leo's strong objections.

When the President collapses on the eve of his State of the Union, it's diagnosed as the flu. But when the First Lady cancels a trip and rushes home to look after him, Leo suspects the first family is hiding something about Bartlett's medical condition.

The West Wing staff are feeling malaise as it seems they never get anything accomplished. Meanwhile, a leaked memo is a land mine that could embarrass the administration.

A stealth fighter is shot down over Iraq, leading to Bartlet ordering a military rescue as Toby worries about his brother trapped on a space shuttle orbiting the Earth. CJ deals with the ramifications of misleading the press about the rescue as the staff prepares for a town hall meeting that night. The town hall meeting goes well until the President leaves...and shots ring out.

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.

The President and Leo deal with reports of a planned terrorist attack, but more shocking is who is behind it. Sam receives an anonymous package with bad implications for the campaign. C.J. chafes under her Secret Service protection.

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.

After Bartlet gives a campaign speech at an Indiana farm, Josh, Toby and Donna are left behind by the presidential motorcade and must work their way across the state with the help of the farmer's daughter and, later, a teenage campaign volunteer, enduring many setbacks along the way. Josh and Toby obsess and bicker over how best to play the president's intellectualism, viewed by many as snobbery, against Republican opponent Robert Ritchie's "regular guy" persona, while Donna must keep them on track and communicate with the real Americans they encounter along the way. Back at the W.H., the president deals with a terrorist attack at an Iowa college swim meet, meets with Leo, Nancy and Fitzwallace to discuss how to handle the prospect of the U.S. and/or Israel being accused of a conspiracy in the assassination of Qumari defense minister Abdul Shareef, and interviews secretarial candidates, including a second round with Debbie Fiderer; the wandering party finally arrive at a city with an airport (presumably South Bend) and stop briefly at a nearby hotel, where they learn about the Iowa attack and Donna chastises the two men for caring only about the campaign and not the people it affects; later in the hotel bar, Josh and Toby meet a man trying to figure out how to pay his daughter's tuition to Notre Dame, and he inspires them to initiate new tax policy.

Donna teaches Toby and Josh an important lesson as their trek homeward continues; Sam staffs the President in Josh's absence and welcomes an old friend home; Bartlet hires a secretary and C.J. finds a Big Brother for Anthony; the situation in Qumar continues to escalate; Bartlet gets spooked by a photo op as the Dow continues its dive; and a pipe bomb kills 44 students at a Midwest university swim meet.

Josh and Toby have a plan to make college cheaper. Leo starts talking to a lawyer about the Shareef assassination. A judicial ruling on third-party candidates has troubling implications for the campaign.

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.

Women's groups, by default including the majority of the First Family, react passionately as a renowned female fighter pilot is sanctioned for an affair with a senior officer. Meanwhile Sam prepares for his campaign.

The president, first lady and w.w. staff travel to Orange County, Calif., to campaign for Sam's bid to win the 47th District congressional seat -- the Nov. winner in the heavily Republican district was, amazingly, a liberal Democrat who, more amazingly, had died a few weeks prior. The president orders Toby to fire Sam's campaign manager, a staunch realist, and take over the campaign with a more idealistic approach. Some conservative voters approach Andrea Wyatt in a bar and give her grief about her out-of-wedlock pregnancy, and Toby and Charlie step in forcefully, landing them in jail. Donna talks, on behalf of Sam's campaign, with a state labor leader who turns out to be a Communist.

Military action in Africa has unforeseen repercussions. Sam and Toby work together on the Orange County Campaign. Will has to find his leadership skills quickly as he is left with no one but interns to prepare remarks on the dry subjects of Taxes.

The assassination of Shareef threatens to become public, the president speaks at Zoe's graduation, and the unthinkable happens.

In the wake of his daughter's kidnapping, Bartlet must make a decision between being a father and being President.

Seven hours have passed since Zoey's kidnapping and and the Republicans are in charge of the White House. Rifts are appearing in the leadership of both parties further complicated by the arrival of a ransom note demanding the release of terrorists.

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.

The president and staff are about to head for Brussels to sign an international free trade deal that Josh has just spent a lot of time and effort negotiating, to nearly everyone's satisfaction; at the 11th hour, the CEO of an IBM-like company tells Josh that the first effect of the new agreement, of which his company is a huge beneficiary, will be the immediate transfer of 17,000 programming jobs to India; the head of the communications workers' union, which is representing the affected programmers, brings one of the programmers to Josh's office, and they refuse to leave, leading Josh to question the underlying adverse effects of the trade deal. Throughout the episode, Ryan tries to make Josh care that he's completing his internship that day, while Donna pesters Josh to bring her on the Brussels trip in an effort to make her a more active player in west wing activities, eventually leading to a trade-off that will mean even bigger things for Donna in the long run.

A fact finding codel to the Middle East is torn apart by an explosion. Key members of the administration and their loved ones are caught in the mess. The President is forced to consider retaliatory military action in the unstable area, with possible repercussions that could last decades.
