Disinformation and conspiracy theories have reached a level unwitnessed since the turmoil of the 1930s. Feature documentary, "How To Build A Truth Engine", portrays a crack-team of investigators from the fields of technology, journalism, folklore and neuroscience who show that if you hack the information feed, you can hack somebody’s mind. Following their personal journeys they take us from the information battlefields into the inner workings of the human brain and show how - through us - a web of lies can change reality.
