The story takes place in a beautiful world where all mammals coexist harmoniously. Judy the rabbit (voiced by Ginnifer Goodwin) has dreamed of becoming a criminal policeman who punishes evil and promotes good since she was a child. With wisdom and hard work, Judy successfully graduated from the police academy and entered the Zootopia Police Station. Little did she know that this is the territory of large carnivores. As the first and only small herbivore, what kind of story will Judy encounter? Recently, there have been a series of missing animal cases in the city. While all the police officers are committed to investigating the truth of the case, Judy is assigned by the chief (voiced by Idris Elba) to become an insignificant traffic policeman. One day, the rabbit on duty met a fox named Nick (voiced by Jason Bateman). The two did not know each other, and then accidentally accepted the task of finding the missing Mr. Otter. If Mr. Otter cannot be found within two days, Judy must voluntarily leave the police station. Judy finds Nick, and the two join forces to reveal a shocking secret hidden in Zootopia.
