Based on real-life events, the mystery of the Roswell UFO and its passengers is as compelling as it is controversial. New Mexico, 1947. Mac Brazel finds unidentifiable wreckage scattered across his farmland. Intelligence officer Jesse Marcel is summoned from the nearby Roswell Air Force base and sensationally declares the debris is from a crashed UFO. But no sooner has the story broken than it's silenced by the Pentagon. And so begins one of the greatest mysteries of modern times.
