On the eve of Bartlet's final debate of his career, Toby is skeptical that Bartlet is prepared to go head to head with his popular Republican rival, Robert Richie.

The White House staff celebrates after Bartlet's landslide defeat of Robert Ritchie, but Bartlet wasn't the only winner -- Horton Wilde, the deceased Congressional candidate also won his race. This puts Sam in a bad position since someone leaked that Wilde's widow would be able to take over her late husband's seat. Toby's ex-wife, Andy Wyatt, also won her seat with 85% of the vote, but Toby worries how her pregnancy will affect her career. Meanwhile, a coup is brewing in Venezuela; and Bartlet tries to share a romantic night with Abbey to celebrate his victory.

The elections have finally wrapped up, but Hoynes is already planning for the next election, as well as the Senate minority leader, which is plotting to delay the president's legislative agenda. Meanwhile, when the 15 year-old son of an Iranian leader needs a heart and lung transplant and needs to come to the U.S. for the surgery, complicated politics threaten to interfere. Also, Toby tries to repay a Congresswoman whose proposal helped aide Bartlet's victory, but was damaging to the Congresswoman in the polls.

Sam packs up for California to begin his campaign, leaving Toby without speechwriting help. Sam suggests that Will Bailey, a skilled campaign manager to take over his position.

To do so, Josh dispatches Donna to hunt down a freshman senator while Josh deals with a Senator who will only vote with the White House if they agree to fund a medical study on the efficacy of prayer. Meanwhile, Danny continues to get closer to the truth behind the Sharif affair; and Charlie sets out to help a soldier's family who is in need of food stamps.

C.J. reluctantly returns to her hometown of Dayton, Ohio for her 20-year high school reunion, and ends up enjoying herself when she bumps into a handsome former classmate. However, her enjoyment is cut short when C.J. finds herself in the middle of a sad family crisis ? her father has been diagnosed with Alzheimer's disease. But as C.J. deals with all the emotion, she constantly feels the need to check up on Toby who's running the press briefings in her absence.

Bartlet's second inauguration is only less than a week away, but the staff has to re-write his inauguration address after an escalating genocide in Africa leads Bartlet to consider using force to end it.

As Air Force One prepares to land at Andrews Air Force Base, a front-wheel light indicator fails to go off, meaning either the light is burnt out or something potentially dangerous. Upon hearing this, C.J. has to keep the news from a plane full of reporters and keep them off their cell phones at the same time while the crew checks out the problem. Tensions begin to rise both in the air and on the ground as people begin to wonder if the plane has been tampered with. Meanwhile, Josh and a Republican Congressman work on a Chesapeake Bay-cleanup bill.

When aballoonman opens fire in the press briefing room, the secret service puts the staff on lockdown until the situation is under control.

Meanwhile, poker night also continues despite the lockdown, but Bartlet keeps getting interrupted after a spy plane is shot down over Russia.

During his first day on the job, Joe Quincy is given three pieces of information and as he pieces them together, he uncovers a scandal that affects the upper-administration. However, the staff, thinking the leak is small and containable, isn't aware that the leak is only the beginning of a larger, more damaging problem.
