Don continues to conceal his increasingly complicated personal life. Meanwhile, Peggy (Elisabeth Moss) pines for the absent Pete - still on his honeymoon - while fending off the advances of several of the men of Sterling Cooper.

The festive Christmas spirit at the annual White House tree-lighting celebration is dimmed when the President learns that Christian relief workers have been jailed in Islamic Northern Sudan. Bartlet welcomes his three independent daughters, Zoey (recurring guest star Elisabeth Moss), Liz (recurring guest star Annabeth Gish) and Ellie (recurring guest star Nina Siemaszko), and is surprised to learn that Liz's husband, Doug Westin (recurring guest star Steven Eckholdt), wants to vie for Congress in New Hampshire. Meanwhile, when the licenses of some doctors in Oregon are suspended after they administer drugs in an assisted suicide, Toby tries to keep the President from being bogged down in a debate--and clashes with Will, whom he sends to convince the Vice President to address the political juggernaut instead.

The President's staff wrangles with new Speaker of the House Jeff Haffley (Steven Culp) over the pending federal budget. Meanwhile, Toby dispatches former Supreme Court clerk and personal friend Joe Quincy (recurring guest star Matthew Perry - "Friends") to check on the condition of stricken Chief Justice Roy Ashland (Milo O'Shea), an elderly Supreme Court icon who has Washington wondering if he will finally resign. With the budget deadline quickly approaching, aggressive advisor Angela Blake (recurring guest star Michael Hyatt) faces a mighty challenge as she tries to work out an agreement that could compromise Bartlet's campaign promises. But the President is also focused on a crucial national television interview that Zoey (recurring guest star Elisabeth Moss) has agreed to tape with a well-known newswoman, Diane Mathers (Kathrin Lautner), who has a knack for exposing raw emotions.

As the White House reels from the kidnapping of Zoey (recurring guest star Elisabeth Moss), the youngest daughter of Democratic U.S. President Josiah Edward Bartlet (series star Martin Sheen), the government is temporarily passed from the distraught Bartlet to the Republican party--specifically Speaker of the House Glenallen Walken (recurring guest star John Goodman - "Roseanne," "Barton Fink")--due to the prior resignation of Bartlet's Vice President. First Lady Dr. Abigail "Abbey" Bartlet (series star Stockard Channing) staunchly supports her husband, but the trauma of potentially losing their child forces her to confront Bartlet with the harrowing notion that the crisis was the direct result of the assassination of a dangerous foreign official he ordered months ago. As always, professorial Chief of Staff Leo McGarry (series star John Spencer) serves as Bartlet's political and emotional buttress. Ever present is highly regarded Deputy Chief of Staff Josh Lyman (series star Bradley Whirford), whose capable a

In the season finale, Bartlet confronts a national crisis on the night of his daughter Zoey's (recurring guest star ELISABETH MOSS) graduation from Georgetown University, forcing him to shut down Washington, D.C., and order a fleet to the Persian Gulf. Bartlet also considers executive action that would have been unthinkable just hours earlier. In the midst of the administration's greatest challenge, a conflicted Toby still finds time to savor a personal milestone.
