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.

A possible third-party candidate threatens to upset the President's lead in the polls. As Qumar threatens to blame Israel for Shareef's death, Leo must convince the Israeli ambassador not to respond. Charlie teaches his new ward a lesson in basic government. When the committee in charge of presidential debates rules that there will only be two, Sam and CJ propose a risky strategy.

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.

Toby falls prey to a practical joke by the rest of the staff, after which everyone but Leo takes off for the debate in San Diego. Sam makes a side trip to Newport Beach to explain to the congressional campaign manager of the late Horton Wilde why the campaign has to fold even though Wilde is still on the ballot; what Sam doesn't expect is a stalwart named Will Bailey who, determined to keep the ideas of the campaign alive, continues to hold campaign events and do door-to-door canvassing. In San Diego, a nervous w.w. staff readies itself to spin for the president, but when Bartlet and Richie go head to head in a unique debate format, Bartlet tears Richie apart on states' rights, education, taxes, etc., by being precisely the intellectual snob everyone had accused him of being and using it to his own advantage. Back in DC, Leo and Jordon Kendall meet with the Qu'mari ambassador to the U.N., and Leo warns Qu'mar to back off its campaign to charge Israel with the assassination of Defense Minister Abdul Shareef. After the debate, Sam returns to Newport to meet once more with Will at a bar, during which Sam makes a surprising offer.

As results come in across the country, Sam is focused on a single congressional election that will determine his own future. After realizing she accidentally voted for the Republican nominee, Donna tries to find a Ritchie supporter who will "swap votes" with her. The President tries to hide a recurrence of his M.S.

Sam finds himself in a tricky position after the election in Orange County takes an unexpected turn. Toby and his ex-wife also find themselves in a delicate position, but decidedly one of their own making. And CJ tracks down the self aggrandizing source of some Process Stories.

It is the day of Bartlet's second inauguration and yet the celebrations stutter as the staff are stunned by a betrayal in their midst.

Will struggles to find the words when the Inauguration speech seems to avoid current heart breaking issues.

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 President, C.J. Cregg, Will Bailey, and others are returning from a long flight overseas. As Air Force One is about to land, the indicator light for the nose wheel fails to come on, prompting pilot Colonel Jessie Weiskopf to call off the landing, and notify the President of the possibility of terrorism. The White House Press Corps is on board, therefore CJ and Will must keep the story under wraps, due to it being a world market event. This becomes a challenge when a F-15 Eagle jet is sent to inspect the nose wheel on AFO. Meanwhile on the ground, Josh is working with Congressman Tom Landis (R-MD) on legislation to Clean-up Chesapeake Bay, which angers Congressional Democrats. Toby meets with Congressman Mark Richardson (D-NY) who has introduced legislation to reinstate the draft, furthermore Toby notifies the Congressman a soldier from his constituency was killed in action in Equatorial Kundu. Donna works with members of the 1st Airlift Squadron, 89th Airlift Wing to learn about "Angel Maintenance," in order to brief CJ, when she returns. Angel is the code word for the President's plane.

Trying to participate in a late-night staff poker game proves difficult as news arrives that an unmanned U.S. spy plane has crashed in a remote part of Russia, and Bartlet and Leo have to deal with an incensed Russian President Chagorin and convince him via phone to let the military go in and recover the plane; C.J. obsesses over the fact that on the exact moment of the spring equinox (today), you can stand an egg on end; Toby and Will have a card-flipping contest in the press room, during which someone from the street fires several bullets into the room; Debbie must "crash" the West Wing for the first time when the bullets fly; at the same time, Josh is interviewing associate counsel applicant Joe Quincy, and there's something about the well-qualified lawyer that bothers Josh, which he deduces during the lock down.
