Mr. Fox moves to a treehouse to escape Mr. Dog, invites friends to a house party, and steals a ladder to make his home accessible. Mr. Dog, drawn by the scent of soup, climbs the ladder, eats the soup, and falls asleep inside. When Mr. Fox returns, he's startled by Mr. Dog, who then scares away the arriving guests. A chaotic tumble ensues as Mr. Dog falls off the ladder with some of the guests. Mr. Fox eventually convinces his friends of his innocence and hosts a successful party on the ground, free from canine interruptions.
