In 1915 18-year-old Alan Farmer, a country blacksmith, joins the Royal Flying Corps, and meets Charles Gaylion, an upper-class officer who transferred in. Mistaken for an seasoned pilot, Alan is taken up in a training plane he cannot land.
Alan's training advances well, but he has to learn both military and flying skills, while Charles has already completed his pilot's training. On a training flight, Alan's engine fails on take-off, and he crash-lands the plane in a field.
