A single rabbit mother rescues a gravely wounded wolf clan lord, then brings her luck-blessed little bunny into the rigid, hierarchical Wolf Castle. At first, the entire clan ostracizes and mistreats them due to their racial differences. But the soft, sweet lucky rabbit, through her innocence and healing charm, wins over the four aloof wolf brothers one by one, changes the stubborn old grandmother's heart, and repeatedly foils the villains' schemes. In the end, the fierce wolf clan wholeheartedly embraces the rabbit mother and daughter, and the two become the beloved darlings of the entire family.
