Orphan Tangtang is abandoned by her uncle and aunt, and on a rainy night, she attempts suicide before being rescued by cold-faced CEO Zhan Beiting. Tangtang is naturally able to understand animal speech, successively seeing through crises such as a bomb under a car, her third uncle's suicide, and her grandfather's brain disease. Feeling sorry for her plight, Zhan Beiting officially adopts Tangtang and spoils her as the apple of his eye. With her special ability, Tangtang assists in solving cases, roots out evildoers, invites a national medical saint abroad, and heals everyone in the Zhan family along the way. In the end, Tangtang firmly stays in the Zhan family and welcomes a fulfilling happiness.
