Once content to duel it out here on Earth, the eternally scrappy Tom and Jerry now boldly go where no cat and mouse have gone before, when they get trapped on a spaceship bound for Mars. After their mistaken mission goes hilariously out of control, the tables are turned on Tom when, thinking him a giant outer space monster, the Martians attack! But what really bristles the cat’s whiskers is Jerry being hailed as the Martians’ long-lost supreme leader! Will the duelling duo put their differences aside long enough to save Earth from invasion? They may need all of Tom’s nine lives to succeed in this extraterritorially funny adventure.
