US Air Force colonel Glenn Ford has a dilemma on his hands. He knows for a fact that two jets under his command were last seen chasing a UFO. But the military higher-ups have no intention of filling Ford in on further developments. Despite these stonewalling tactics, Ford steps up his own investigation--and uncovers an insidious right-wing plot to overthrow the government. Bradford Dillman, who has probably made more TV movies than Karen Valentine even, costars in The Disappearance of Flight 412. The film was telecast two months after Watergate, a time in which "conspiracy" movies were breeding like rabbits.
