Lieutenant Robert Banks Buddy Rogers, a young American aviator in the Lafayette Escadrille, on leave in Paris, meets Mary Gordon Jean Arthur, a young American living abroad. Their romance is cut short by his return to the front. In an air battle, Robert brings down and captures von Baden, nicknamed the Grey Eagle Paul Lukas, and takes him to Allied headquarters in Paris, to obtain intelligence on German plans. Mary, ostensibly a spy for the Germans, drugs Robert, who awakens to find that his uniform has been stolen by von Baden. Later, in another air conflict, von Baden is wounded, but shoots down Roberts aircraft. The German rescues him, however, and takes him to an Allied hospital, assuring him of Marys love; his faith in her is restored when Robert learns that Mary is actually an American spy.
