House is recruited by the CIA to help diagnose a deathly ill agent with an unknown illness. The agent’s medical case is being spearheaded by Dr. Samira Terzi (guest star Michael Michele), who offers up very little information about the agent’s history or previous assignments. With limited information to go on, House uses some unorthodox methods to try to crack the code and determine a diagnosis in time to save his mystery patient’s life. Meanwhile, Foreman faces resistance from the remaining six fellowship candidates when they question his judgment and argue over the diagnosis of a female drag car racer who passed out after a race.

A documentary film crew is chronicling a teenager with a major facial deformity who opts to undergo a dramatic reconstructive procedure. When the patient suffers a heart attack just prior to the surgery, House and the team are called in to determine the cause, since the surgery cannot proceed until the patient’s cardiac condition is diagnosed. With the film crew covering their every move, Cameron and Chase are especially self-conscious, and House looks for ways to escape from the cameras. Meanwhile, House finds himself distracted by several of the candidates vying for a spot on his team, and he questions his motives for having chosen them.
