Dr Richard Shepherd investigates the death of the Clueless and 8 Mile star in December 2009, which was due to pneumonia, anaemia and multiple drug intoxication. Dr Shepherd goes back over a 12-month period immediately before Murphy's death, discovering evidence of a woman caught in a triangle between her husband, her mother and a paranoid personality fuelled by prescription drugs. Dr Shepherd carefully picks his way through the autopsy reports and the numerous conspiracy theories that surround the case.
