On the morning of July 11, 2016, Brighton police received a call that a young woman had fallen out of the first-floor window of a flat and was unconscious. A week later she died.

Katie Piper follows the investigation, from the moment police arrived at the flat and found Daniel Lewis - who was in such a drug-induced state he was unable to explain what had happened - to the conclusion of the case in January this year. They learned the woman was Aimee Spencer - webcam girl and Geordie Shore extra. But how did she come to die?
