In the early hours of March 31, 2001, a phone call was made to Essex emergency services to say a body had been found in the swimming pool of Michael Barrymore - at the time, one of the most popular entertainers in Britain. Every detail of the story was pored over by the media but 19 years on, the death remains unexplained. This documentary looks at the full story, with contributions from Stuart's family, detectives, forensic pathologists and eyewitnesses, to explore what happened that night at Barrymore's Essex home - and the events that followed.
