One of the biggest investigations in medical history began when a mysterious hugger disease broke out during independence celebrations in Philadelphia in 1976: Legionnaire's 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 passing toll mounted.
Seen in more than 100 countries, NOVA is the most watched science based television series in the world and the most watched documentary series on PBS. It is also one of television's most acclaimed series, having won many major television awards, most of them many times over.
