Forensic pathologist Dr Richard Shepherd investigates the death of the model and actress, who died in February 2007 at the age of 39 from a drug overdose. The evidence revealed by her autopsy bears testimony to the addictions and behaviour that blighted her life, while also shedding light on the unusual cause of a mystery infection that contributed to her death and uncovering a previously undiagnosed condition that could explain many of the tragic events of her life.
