The American Volunteer Group, or Flying Tigers, fight bravely for China's freedom despite the face that they are greatly outnumbered. Squadron leader Jim Gordon (John Wayne) gets a new recruit when Woody Jason joins the group. Wood signs up only because he needs money to pay off a breach-of-promise suit. His egotism and mercenary motives gain him the ill-will of fellow fliers. He further antagonises them by stealing Jim's girl, Brooke (Anna Lee), a Red Cross worker.
