Based loosely on the once-popular nursery rhyme. A fair is in progress, with refreshments, entertainment, and other activities. As the rest of the crowd is watching one of the acts, the titular Tom steals a pig from another little boy and runs off. He tries to hide, but he is chased by the crowd. The pig also proves difficult to control. Tom, the little boy, and the crowd run from place to place.

A family moves out to the 'peaceful' suburbs where everything goes wrong, including the mother-in-law moving in.
