Before the United States enters World War I, some American youths volunteer for the French military. Subsequently, they become the first U.S. fighter pilots and form a squadron known as the Lafayette Escadrille, whose exploits and heroism become the stuff of legend. This fictional version follows a laconic Texas rancher, an eager Nebraska kid, a Black boxer already in France, and a New York swell, as they arrive green for training, get their baptism by fire when German planes ambush them on their first mission, and graduate to heroics. Rawlings, the Texan, falls in love with a young woman he meets at a brothel.
