Single mother Su Wan was fired for protecting animals, and brought her daughter Duo Duo to the struggling Qinghe Zoo. Who would have thought that her soft and cute daughter could actually understand animals' inner thoughts: the white tiger fears the cage, the monkey loves hiding keys, and the black bear misses its old home. Faced with successive hardships and calculations, Duo Duo milky-voicedly backed up her mom. Su Wan relied on her professionalism and resilience to guard the park, and Li Chenghui also always guarded the mother and daughter. As Su Wan's identity as a chairman's daughter was revealed, those who once looked down on her panicked completely. This time, she will not only guard the animals' home, but also lead her daughter to live out her own happiness.
