William Cooper spent decades broadcasting warnings about secret governments, UFO cover-ups, and hidden agendas on his shortwave radio show, The Hour of the Time, and his book Behold a Pale Horse became a foundational text for a generation of conspiracy researchers. This film traces his path from Navy veteran to self-styled truth-teller, using clips of his broadcasts and interviews with people who followed his work to explain why his claims about assassinations, secret societies, and extraterrestrial contact still circulate online decades later. It follows him through his growing estrangement from mainstream media, his disputes with fellow researchers, and the 2001 standoff with Arizona police that ended his life. Rather than simply cataloguing his theories, the film asks what made his voice resonate with so many listeners and why his ideas kept spreading after his death. Archival radio audio carries much of the film, letting Cooper argue his own case in his own words.
