Dean Haglund is best known for playing Richard Langly, one of the Lone Gunmen on The X-Files. In recent years has capitalised upon that role and has become closely identified with the realm of the paranormal and the world of conspiracy theories. The documentary The Truth Is Out There follows Dean as he travels the US and attempts to discover just what it means to search for the truth in a world where conspiracies theories, untruths and fake news abound. The documentary directed by Phil Leirness, humorously takes the viewer on a journey of discovery, talking to those who believe that the world is not what it seems.
