House and Park treat a patient, Benjamin, who collapsed after making a surprisingly large charity donation, and come to suspect that the altruistic behavior is a symptom of a deeper disorder. When the patient offers to donate an organ for another patient, the doctors must convince Dr. Adams to help them confirm whether Benjamin is in his right mind or not.
