While trying to figure out why a young patient won't stop bleeding after a car wreck, House takes Cuddy's challenge and goes off Vicodin for a week in exchange for no clinic duty for a month. If House and his team can't determine the source of his patient's blood loss, the 16-year-old car victim will die in a matter of days. As House's withdrawal symptoms become more and more severe, his patient directives for his patient are more harsh and risky than usual, and Foreman and Cameron are afraid he may not be thinking clearly enough to save the patient's life.
