Plasticine animation of Wallace and Gromit, inventors of all manner of useful devices. Gromit (a dog) finds himself being pushed out of his room and home by a new lodger who is actually a ruthless criminal (and a small penguin). The penguin is planning a robbery and needs to use Wallace and his mechanical remote controlled trousers to pull off the raid. However, Gromit is wise to the penguin and comes to the rescue.

Wallace and Gromit have run out of cheese and this provides an excellent excuse for the animated duo to take their holiday on the moon, where, as everyone knows, there is ample cheese.
