In his first term as President, Josiah Bartlet and his eager group of staffers battle day to day issues and attempt to pass legislation through back channels and dealmaking. Among the last moments of this particular year are Sam Seaborn's well-intended relationship with a call-girl, the breakdown of White House Chief of Staff Leo McGarry's marriage and Charlie Young's courtship with Zoe Bartlet, the President's youngest daughter.
The President finds himself stalled, concerned with re-election and not focusing on reform. Finally, McGarry rouses the President into action and the team begin to initiate serious reform. At the apex of their progress, however, the column comes under fire from White Supremacists targeting Charlie Young.
