Troublemaker Conrad and control freak Sally live with their mother Joan in a house in Anville. Joan works for neat-freak Hank Humberfloob at his real-estate company and she is invited to host a party at her house. Her boyfriend Larry Quinn wants to ship Conrad to a military school. One day, she leaves for work and Conrad and Sally then meet up with a strange cat, who tries to teach them the proper way to have fun.
Maybe next time they shouldn't pick an adult movie director to adapt a children's book! Still a good film, though.
