In a world populated by anthropomorphic mammals, Judy Hopps, a rabbit
from rural Bunnyburrow, fulfills her dream of becoming the first rabbit
officer in the police department of nearby city Zootopia. However, upon
arrival, she is assigned parking duty by Chief Bogo, an African
buffalo, who doubts her potential due to her being a rabbit and thus
smaller than most of the large animals on the force. During one of her
shifts, she meets Nick Wilde, a con artist fox.
Hopps abandons her shift to arrest a thief, Duke Weaselton. She is
reprimanded by Bogo and nearly fired until Mrs. Otterton, an otter,
arrives pleading for help locating her missing husband one of many
animals recently missing in Zootopia. To Bogo's dismay, Hopps
volunteers and agrees to resign if she cannot solve the case within 48
hours. She sees Wilde in the last known photo of Otterton and tracks
him down, coercing him into to assisting her with the investigation.
After acquiring Mr. Otterton's license plate number, Hopps and Wilde
track the vehicle to Mr. Big, an Arctic shrew crime boss. Mr. Big
informs the pair that Otterton, his florist, had gone savage and
attacked his chauffeur Manchas, a black jaguar. Hopps and Wilde locate
Manchas, who mentions "night howlers" were responsible for attacking
him before he goes savage and chases the pair out of his home. When
Bogo and his reinforcements arrive, Manchas disappears. Bogo demands
Hopps resign, but Wilde takes a stand, insisting they have 10 more
hours to solve the case. As the pair leaves, Hopps learns from Wilde
that he was bullied by prey animals as a pup and became a criminal,
believing he would be stereotyped as one no matter what due to being a
Wilde realizes that the city's traffic camera system may have captured
Manchas's disappearance, and the pair consult Assistant Mayor
Bellwether, a sheep. They identify the captors as wolves, hence "night
howlers". Hopps and Wilde locate the missing mammals (including Mr.
Otterton) at Hillside Asylum. All are predators, and all have gone
savage like Manchas. The two discover Mayor Lionheart consulting with a
doctor about the predators' condition. The pair escape with the
evidence and the police swarm the area, arresting Lionheart.
Having developed a friendship with Wilde throughout the case, Hopps
requests that he joins the Zootopia Police Department and become her
partner, which Wilde happily considers. However, during a press
conference, Hopps mentions that the savage animals are predators and
argues they have gone back to their "natural state." Wilde is hurt and
angrily walks out on her offer. Fear and discrimination against
predators spreads across Zootopia, and a guilt-ridden Hopps resigns.
During this time, pop singer Gazelle holds a peaceful protest and
publicly asks for the harmonious Zootopia she loves to be restored.
Back in Bunnyburrow, Hopps learns that "night howlers" are flowers that
have a severe psychotropic effects on mammals. Hopps returns to
Zootopia and reconciles with Wilde. They locate Weaselton and learn
that he has been collecting night howlers for a secret laboratory. The
pair discover the lab and find ram scientists creating a night howler
serum, which has been injected into predators via dart guns. Hopps and
Wilde race to the ZPD with the evidence, but the rams pursue them.
Just short of the ZPD, the pair encounters Bellwether, who tries to
take the evidence. Realizing Bellwether is the mastermind of a
species-supremacist conspiracy, Hopps and Wilde try to flee, but
Bellwether shoots a dart at Wilde and calls the ZPD for help. Wilde
becomes savage and corners Hopps, but it turns out the pair were acting
and had swapped out Bellwether's darts for blueberries. With
Bellwether's confession recorded on Hopps's carrot pen, the two have
enough evidence to unravel the conspiracy.
Some months later, Hopps is reinstated into the ZPD. The savaged
mammals are cured. Lionheart is cleared of all charges and is
reinstated as mayor. Wilde joins the ZPD as the first fox officer and
Judy's new partner. In the final scene, all of Zootopia enjoys a
performance by Gazelle, who dances with four tigers.
