Chronicling the most expensive serial killer investigation in Canadian history, THE PIG FARM KILLER is a feature-length documentary which delves deeply into the life of Pickton and recounts, in gory detail, the long-running investigation and capture of this vicious, remorseless killer. But while Pickton ended up behind bars, his crimes went undetected for years, and one main question remains how did an unsophisticated pig farmer-turned-serial killer from Vancouver hide in plain sight for so long? Providing answers to this question, THE PIG FARM KILLER features interviews with acquaintances and employees who reveal, on-camera, that they kept key information from police for years, vocal recordings of Pickton himself, lending new insight into the mind of a deranged killer and revealing interviews with police officers who speak frankly about key moments that they feel could have changed the course of the investigation -- and the course of history.
