Fan Keke, the youngest female pilot of the Chinese Air Force, was shot down in an air battle and fell behind enemy lines. She disguised herself as a village woman, but discovered that the village she was in was actually a supply point for the Japanese army's secret airport. With the expertise of a pilot, she calmly drew a map of the airport and planned a desperate arson using only matches and lard. In a desperate situation, this "genius" used the earth as a battlefield and vowed to use flames to tear through the invaders' disguise.
