Inspector Gallagher Willard Kent of the United States Department of Commerce views a number of crashes and disappearances of GoeringGage Aviation Corporation aircraft as suspicious. With United States Army Reserve test pilot Jerry Blackwood John Carroll, Gallagher visits the GoeringGage company. Jerry test flies GoeringGage aircraft but finds nothing wrong. When a severely injured passenger from a crash, claims a mystery aircraft attacked them, the owner, Henry Goering Henry Hall hires psychiatrist, Dr. Norris John Elliott, to question the man. Dr. Norris believes a psychotic exWorld War I flying ace, whom he dubs Pilot X, may be behind the attacks. With the help of Blackwood, Goering and Norris assemble a group of five exflying aces living in the area who may have a connection with the mysterious Pilot X. He recruits German Lieutenant Baron von Guttard Hans Joby, French Lieutenant Rene Le Rue Gaston Glass, British Captain Roland Saunders Pat Somerset, Canadian Lieutenant Douglas Thompson Wheeler Oakman and American Lieutenant John Ives Reed Howes. The group meets in a mansion to plan how to confront the mysterious Pilot X. One pilot, however, von Guttard comes under immediate suspicion when Goering is uneasy with son Carl Leon Ames, an exGerman prisoner of war. On their first patrol, Pilot X attacks, killing von Guttard. Later that day, Le Rue is killed by Pilot X and the next day, Saunders has a mental breakdown. Blackwood receives a note from Pilot X, asking him to meet him in the sky at six oclock the next morning. Thompson, meanwhile, receives a similar note but Pilot X, who is on the airfield, paints an X on Thompsons aircraft. Blackwood mistakes Thompson for Pilot X, and kills the Canadian. When a paint can is found in Ives locker, all accuse the American ace of being Pilot X. That night, Dr. Norris calls the elder Goering, telling him that he knows who is Pilot X, but is murdered. Gallagher believes Blackwood is Pilot X, and sends Ives and Saunders after him. Helen Gage Lona Andre, Henrys ward, however, first finds part of Saunders goggles near Norris dead body, then finds the other half in his aircraft. Crazed, Saunders, takes off after Blackwood with Helen trapped on his aircraft. Once in the sky, Pilot X appears and attacks Saunders, wounding him. In a fierce dogfight, Pilot X attacks Blackwood but is shot down. In the wreckage of Pilot Xs aircraft the body of Carl Goering is discovered along with a photograph of Carl in a German uniform. He was not a prisoner of war, but deserted and joined the German Air Force. With the mystery solved. Blackwood and Helen realize that they are attracted to one another and embrace.
