Old Tom is a mischievous stray cat, that loves getting into trouble. With his owner Angela, his best friend Lucy and Angela's snobby friend Lavinia in tow, can Old Tom manage to control his behavior or will his antics get him into more trouble?
The Queen, wanting to see someone different at her next garden party, choses Angela and Old Tom at random. Angela is delighted, but gives Old Tom a crash course in manners, just in case. The garden party begins, but the Queen doesn't want to go, because her dog doesn't seem well. Meanwhile, Old Tom upsets several party guests and seeks refuge from them in the palace. There he annoys the Queen's dog, which chases him around the throne room. The Queen enters and, delighted to see her dog full of life again, decides to go to the garden party after all - with Old Tom as her guest of honor.
