Food delivery rider Lu Ming is unexpectedly caught up in a murder case at a zoo and inexplicably becomes a murder suspect. By a twist of fate, he awakens a supernatural ability to understand animals' thoughts. Brother Biao, a hamster who speaks with a strong Northeastern Chinese accent; a bald-headed gibbon who loves throwing feces; and a Doberman who looks like a tough guy but speaks in a high-pitched, cutesy voice—all these drama-loving animals become his secret informants. To clear his name, Lu Ming takes over a bankrupt zoo saddled with two million yuan in debt and becomes its acting director. He fights the hidden villains coveting the land and relies on his animal intelligence network to track down the real killer, while also facing the probing questions of his ex-girlfriend Lin Xiaoxiao, a criminal police officer. The stories of humans and animals intertwine as comedy, suspense, and multiple twists unfold one after another.
