A wolf "Huihui" chased down the mountain by the wolf pack stumbles into a Dog Village and is mistaken by a Samoyed "Dundun" for his older brother lost for ten years; to repay the favor of a meal of dog kibble, he replaces Dundun on stage to fight the Dog King, ending up acting more and more like a brother and slipping up more and more in the fight, until finally trading one year of herding sheep to buy back his brother, making his way straight from a "fake brother" into "the wolf of my family".
