It was the most expensive serial killer investigation in Canadian history. And ultimately, a killer was put behind bars. But the crimes of Robert "Willie" Pickton went on for years, and many questions are still unanswered. How was an unsophisticated pig farmer able to murder so many women without getting caught? And how did he get away with it for so long? This documentary provides answers, by delving deep into the life of Pickton and his closest associates during the years that women were going missing from Vancouver's Downtown Eastside. Several former acquaintances and employees reveal on-camera that they kept key information from police for years that could have saved many lives, and put Pickton behind bars much sooner. Their revelations paint a chilling picture of life on the farm, where Pickton played white knight to the down and out, creating an ever-expanding circle of need and a conspiracy of silence. It raises the disturbing question of who knew what and when, and whether Pickton always acted alone. The film also contains the voice of Pickton himself and gives insight into the persona he projected to those around him. There is also a chilling first-hand account from a women who got away -- a former prostitute who went to the farm with Pickton and ended up fighting for her life. The jury never heard her story and she has never spoken publicly about it until now. There are interviews with police officers from both the Vancouver Police Department and the RCMP. They offer new insight into what was happening inside the investigation, and speak frankly about key moments that they feel could have changed the course of the investigation and the course of history.
