The lazy and funny Garfield is back! This time Garfield and his owner Jon (Breckin Meyer) traveled to the UK. Along the way, he kept playing tricks, and the master and servant made a lot of jokes. Coincidentally, there is a well-born cat in London who looks very similar to Garfield. By chance, they exchanged identities, and Garfield enjoys the luxurious and luxurious life he dreams of. The aristocratic cat inherits the wealth of its owner and arouses the hatred of its owner's greedy relative Dargis (Billy Connolly). Dargis frequently uses bad tricks and wants to kill him. How should our fake aristocrat Garfield cope with this dangerous enemy?
