Gilda Radner was an icon of American comedy, whose unique characters on hit show Saturday Night Live catapulted her into the nation’s heart.

So what caused her to catch the deadly disease at such a young age and why did doctors miss multiple opportunities to catch it? World renowned medical examiner and forensic pathologist Dr. Michael Hunter leads the investigation to find the answers.
