The gruesome, true story of John Worboys, one of the most notorious serial killers and rapists in British history. His modus operandi was to tell women in his taxi that he had won money and then drug them, rendering his victims unconscious. He was convicted in 2009 for sexually abusing twelve women between 2006 and 2008. His victims are now followed in their fight to get him back behind bars, after he was released due to police failure.
