Three‑year‑old Mopsy ventures alone into the Blackwell werewolf manor to find her birth‑father Nathan with a wolf‑head crest. Gifted with the ability to understand mythical beasts, she defuses a crisis of the guardian wolf, and DNA proves her blood tie with Nathan. Her mother Claire remains missing, while seals of the Wild Realm keep cracking and beast tides loom large. Awakening nine royal marks, Mopsy chases clues of her mother and fights against evil schemes. Rejecting outdated ancient rules, she protects her family with kindness and bravery, mends the seals at last, and the whole family reunites after overcoming all estrangement.
