How a young Wolf moves from the wilderness into human civilization.A Wolf called White teeth was born in the wilderness world, seeing the world of the jungle in its infancy. Later, the she-wolf took him back from the wilderness to his Indian owner, and the human camp life made him perverse and lonely, cruel and heartless, hostile to any race, and even more cynical when sold to Smith.Under Smith's abuse and surveillance, he becomes a fierce Wolf fighter, saved by his new owner Widenscott after a near-death career. His kind love transformed him from a ferocious beast into a faithful pet, and saved the life of his new owner's father from the bad hands, winning the reputation of "Fu Wolf", and spent his old age in peace.
