Tom and Jerry need to learn to work together in order to help Sherlock Holmes with an investigation of a jewel theft. But still, they are cat and mouse!
While carrying on their usual hi-jinks, they inadvertantly stow-away on a spaceship bound for Mars. They meet up with the local Martian residents and cause them to invade the Earth, aided by the "Invincitron", a vacuum-wielding giant robot. Tom, Jerry and their Martian ally, Peep, save the day.
