When Wallace, a brilliant but very oblivious inventor, rents out his room to a penguin so he can pay for his home's expensive mortgage, Gromit, Wallace's loyal mute dog, immediately becomes suspicious. When Wallace is framed for a diamond robbery at the hands of this penguin, Gromit steps in to help... but is then framed for a series of sheep murders by the penguin's partner, a robotic dog named Preston. Teamed with Shaun The Sheep and Wallace's girlfriend Wendolyn, Gromit sets out to clear both their names.
