The Benson boys return to Buckman for spring vacation and concoct a prank involving a non-existent ghost, continuing the practical joke war between the Hatford boys and the Malloy girls.

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.

Once again the Hatford brothers and the Malloy sisters find themselves pitted against each other when embarrassing pictures of the boys turn up in the girls' basement, and the boys try to figure out how to get them back.

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.
