Ace Drummond is a 1936 film serial based on the Ace Drummond comic strip drawn by Clayton Knight and written by Eddie Rickenbacker. It featured aviator Ace Drummond and his adventures in Mongolia. A mysterious villain who calls himself The Dragon is attempting to prevent International Airways from beginning service there, in order to protect the secret of the mountain of jade for himself. It features a dungeon in the nearby monastery, the kidnapping of an archeologist who stumbles onto the secret, his daughter's attempts to rescue him with Ace's help, a death ray The Dragon uses on the airline pilots, a radio system by which The Dragon communicates with his henchmen via the rotation of Buddhist prayer wheels (each transmission concluding "The Dragon commands!"), and a squadron of his own fighter planes. Ace also regularly performs his theme song, "Give Me a Ship and a Song". Never explained is why International Airways selects flying boats for their planned Mongolia service instead of landplanes.
