The main character of the story is Fang, who was born to a hunting dog and a circus-runaway European wolf. Although Fang was raised by a human family, he is a wild animal after all, and is destined to live amongst nature. The story reaches its climax when Fang returns from the circus and faces his foe, a giant brown bear which killed his family.
