It's almost time for the finale of the Autumn Harvest Festival show, but there is a big problem for the competition entrants of the West Wallaby area; hoardes of hungry bunnies are roaming the gardens after dark, consuming the precious vegetables! Luckily Wallace and Gromit (aka Anti-Pesto) have invented the 'Bunvac', a machine that sucks up the rabbits and stores them in hutches in their basement. But one night a strange creature starts to prowl the gardens at night time, terrorizing local people and consuming even more vegetables. Is it just a coincidence, or have Wallace and Gromit managed to create some kind of wererabbit? One thing's for sure, only Wallace and Gromit can save the day (and the vegetables!). A fabulous retelling of the exciting and action-packed adventures of Wallace and Gromit.
