When Cuddy puts the pressure on House to choose the final members of his team, House deliberately assigns the candidates to a particularly challenging case - an uncooperative, over-the-hill former punk rock star with a history of drug abuse and civil disobedience. House informs the candidates their potential future depends on correctly diagnosing the patient.

Meanwhile, Wilson informs a former patient whom he had previously diagnosed with terminal cancer that he is going to live, and the news throws a wrench in the man's carpe-diem lifestyle.
