Eight-year-old girl Lin Manman unexpectedly gains the ability to understand animal language. Facing an aquarium on the verge of bankruptcy, she does not treat the animals as performance tools, but patiently listens to the inner voices of polar bears, sea lions, walruses, beluga whales, and other animals, helping them break out of fear and misunderstanding. Through the joint efforts of her father Lin Haichuan and partners, the aquarium gradually revives from a desolate and endangered state, becoming a beloved animal-friendly venue. The story conveys warm values of respecting life, understanding companionship, down-to-earth entrepreneurship, and growing together.
