Following an emergency landing in the Andes, Race finds himself drawn into an aerial duel with Baron Heinrich von Frohleich, a legendary German fighter pilot from World War I.

However, Race quickly realizes that while the Baron's machine guns are fully operational, his own weapons are unfortunately unloaded.
