村民们要参加一年一度的蔬菜大赛啦，他们培育出来的蔬菜超级棒，不料却招来了害虫——野兔的骚扰。野兔身材高大，神出鬼没，村民们一筹莫展，唯有请来捉兔专家华理士。当然，华理士的爱狗勒密特也在捉兔队伍之列。华理士和勒密特设计出各色各样的捉兔工具，村民以为大可放心时，华理士却犯了一个严重的错误：他竟然错误操作机器，让自己和野兔的思想发生对调，闹剧更加轰轰烈烈。互换了身份的华理士和野兔，如何让自己回到原来的世界，而野兔就注定要被除掉吗？It's 'vege-mania' in Wallace and Gromit's neighborhood, and our two enterprising chums are cashing in with their humane pest-control outfit, "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 outfit has its drawbacks as their West Wallaby Street home fills to the brim with captive rabbits. Suddenly, a huge, mysterious, veg-ravaging "beast" begins attacking the town's sacred vegetable plots at night, and the competition hostess, Lady Tottington, commissions Anti-Pesto to catch it and save the day. Lying in wait, however, is Lady Tottington's snobby suitor, Victor Quartermaine, who'd rather shoot the beast and secure the position of local hero-not to mention Lady Tottingon's hand in marriage. With the fate of the competition in the balance, Lady Tottington is eventually forced to allow Victor to hunt down the vegetable chomping marauder. Little does she know that Victor's real intent could have dire consequences for her ...and our two heroes.
