Steve Rogers and Bucky are stationed at the Great Wall of China when they come across a Jap plot to bypass Chinese garrisons by using hollowed out interior tunnels within the wall. Cap and Bucky meet a mysterious old Chinese man who gives them aid against the Japanese troops. When the old man tells Cap and Bucky that the walls will collapse burying the Japanese, it comes to pass, and Cap finds a coffin with an inscription that he can partially read. Cap and Bucky realize that their benefactor was the long dead ghost of the Great Wall's architect.
