The story is called "The Dragon Princess" and tells the tale of a war between dragons and humans started when the evil dragon king steals the emperor of China's newborn daughter. The war is long and bloody, wiping out all dragons except the dragon king, who retreats underground with the baby princess. Years later, a young samurai hears of a reward for rescuing the princess and killing the dragon king. He finds the dragon king's lair, defeats him, and rescues the princess. When they emerge, the emperor and princess are reunited, and the samurai refuses a money reward, instead asking for the princess' hand in marriage, which the emperor agrees to.
