Dutiful son Bennv writes his mother frequently. Unfortunately, his letters describe his life as the mayor of New York City! When Mrs. Ball pays a visit, Top Cat and the gang create the illusion that Benny is indeed mayor. They ""borrow"" Officer Dibble's police car and stage a key-to-the-city ceremony, a boat christening, a ribbon-cutting ceremony, even a ticker-tape parade. When Dibble finally catches up with them, he doesn't have the heart to shatter Mrs. Ball's illusions, and ends up driving them all to the airport to see the ""mayor's"" mother off.
