Wallace & Gromit: The Curse of the Were-Rabbit

Tottington Hall's annual Giant Vegetable Competition is approaching. The winner of the competition will win the coveted Golden Carrot Award. All are eager to protect their vegetables from damage and thievery by rabbits until the contest, and Wallace and Gromit are cashing in by running a vegetable security and humane pest control business, "Anti-Pesto".
As the event draws close, Wallace finds themselves running out of space to cage the rabbits. He is inspired to create the Mind Manipulation-O-Matic machine to brainwash the rabbits and remove their appetite for vegetables. On his first attempt, a rabbit is stuck to Wallace's head as he uses the machine's headpieces, and Gromit destroys the machine to protect Wallace. The machine appears to have worked as the rabbit shows no interest in vegetables though appears to have gained some intelligence. They name the rabbit Hutch while Wallace begins rebuilding the device.
Over the night, several townsfolk report a giant Were-rabbit tried to eat their vegetables. Wallace suspects that Hutch may be the Were-rabbit and keeps him caged up. Lady Tottington holds an emergency town meeting, in which the hunter Lord Victor Quartermaine offers to shoot the Were-rabbit. However, Lady Tottington persuades the rest of the town to continue with Anti-Pesto's services. Victor, who really seeks to woo Lady Tottington, becomes jealous of Wallace, and later corners him in town as the sun starts to set. To Victor and his dog Philip's shock, Wallace transforms into the Were-rabbit and bounds away. Gromit, who also witnessed the chase, lures Wallace back home to protect him. Victor obtains three "24-carrot" gold bullets from the town's reverend to use against Wallace the next evening.
The celebration begins the next day. Gromit convinces Wallace that he is the Were-rabbit, and Wallace hides himself away. Lady Tottington, who has come to like Wallace, comes to visit as the sun is about the set. Wallace, feeling the change about to start, shoos Lady Tottington away to avoid harming her. As she leaves, Victor arrives and attempts to fire on Wallace with the golden bullets. Gromit creates a distraction to allow Wallace, as the Were-rabbit, to escape, while he is put into a cage by Victor and Philip. The hunter gives chase to Wallace as he heads for the competition. Gromit is able to escape with the help of Hutch, and plans to sacrifice the giant marrow he had been growing as bait to lure Wallace back to safety.
Wallace, as the Were-rabbit, creates chaos at the fair, and Victor is unable to hit Wallace with the bullets. Instead, he grabs the Golden Carrot trophy to use as ammo for his blunderbuss. Wallace grabs Lady Tottington and climbs onto one of the towers of Tottington Hall. Victor gives chase, revealing that he only wants to impress Lady Tottington for her money. When Gromit arrives, Philip attempts to prevent him from interfering, leading to the two into a dogfight using aeroplanes taken from a fairground attraction. Gromit gets the upper hand, sending Philip's plane to the ground, then steers his plane into Victor's line of fire just as he is about to shoot the Golden Carrot at Wallace. The plane takes the hit and starts to go down, whereupon Wallace jumps off the tower, grabs Gromit and sacrifices himself to cushion their fall into a cheese tent. Victor gloats about his victory, but Lady Tottington hits him with her giant carrot, knocking him out into the cheese tent as well, and goes to check on Wallace herself. As the townspeople begin to form a mob to learn the Were-rabbit's identity, Gromit quickly disguises Victor as the Were-rabbit, who is subsequently chased away from town by the mob.
Wallace shortly transforms back to his human self and appears dead, but Gromit uses some Stinking Bishop cheese to bring Wallace back around to good health. Lady Tottington awards Gromit the Golden Carrot for his sacrifice of the giant marrow, and later converts the grounds of Tottington Hall into a safe habitat for Hutch and the other captured rabbits.
