The feud between the Hatford brothers and the neighboring Malloy sisters continues over the summer when they reluctantly join forces to publish a newspaper.

The Malloy girls and the Hatford boys try to outdo each other in a quest to earn money and choose how to participate in the annual Buckman, West Virginia, Strawberry Festival.

Disgusted that a family with three girls moves into the house across the river, nine-year-old Wally and his three brothers declare a practical joke war on the girls.

The Hatford brothers cannot imagine spending Thanksgiving dinner with the Malloy sisters as the practical jokes and rivalries between the two families continue.

As the end of summer approaches, the Malloy girls decide they will really try to get along with the Hatford boys before moving back to Ohio, but after all the practical jokes and competitions of the previous year, the boys just do not trust the girls.
