One of the biggest investigations in medical history began when a mysterious killer disease broke out during independence celebrations in Philadelphia in 1976: Legionnaires' disease. NOVA traces the search for a cause and cure—a search bedeviled by false trails, accusations of incompetence and cover-up, and increasing urgency as the death toll mounted.
