Young Otto Kerchner dreams of escaping his father's Wisconsin dairy farm and becoming a flier like his hero Charles Lindbergh. When a small airport is built on an adjoining property, Otto trades odd jobs for flight lessons and becomes a pilot at 16. When World War II breaks out, he enlists in the Army Air Corps and finds himself a year later high over Germany at the controls of a B-17. Otto and his crew fly 23 missions untouched, but then his world shatters, and he must draw on reserves of faith and courage he never imagined.
