It's veggie-mania in Wallace and Gromit’s neighborhood, and this man and dog team are cashing in with their humane pest-control business, “Anti-Pesto.” With only days to go before the annual Giant Vegetable Competition, business is booming, but Wallace & Gromit are finding out that running a “humane” pest control company has its drawbacks as their home fills to the brim with captive rabbits. Suddenly, a huge, mysterious, vegetable-destroying “beast” begins attacking the town’s sacred vegetable gardens at night, and the competition hostess, Lady Tottington, enlists Anti-Pesto to catch the creature and save the day. However, Lady Tottington’s snobby suitor, Victor Quartermaine, is lurking about and hatching more sinister plans for the creature. Victor’s real intent could have dire consequences for everyone involved, including our two heroes.
