A crack American flying troop has been sent to France, where they await further instructions. They are concerned that their extensive talents will not be put to good use in the war. Major Cowan introduces Lt. McGee as the British instructor for the crew. It turns out the Brit is actually an American, born in the U.S., even though his parents were British. McGee and Larkin are flying partners. Out on a mission, McGee spots a small enemy plane in a searchlight, probably intent on dropping flares to mark targets for bombers. He drives in for the attack successfully, as the enemy plane zooms earthward in flames. During another flight to Epernay, a fellow pilot, Siddons, fades back to a previous stop.
