Ben Healy has divorced his controlling and overbearing wife, before he and his adoptive son Junior Healy move to Mortville, Oregon, a quiet community, as a way to start over. Ben is initially sad to leave Cold River until Junior reminds him that everyone there has been horrible to him his whole life. Before they arrive at their new house, Junior sees a girl roller skating on the sidewalk with a balloon. He pops it with his sling shot and laughs at her as he goes by. He and Ben arrive at their new house, and moments later, dozens of women line up in their front yard, all wanting to date Ben. Meanwhile, Ben's father, Big Ben Healy, moves in with them when he loses all of his money in a bad investment.
When Junior starts third grade, he sees that Igor Peabody is the principal at his new school. Peabody screams at the sight of him and promptly promotes him to the sixth grade, claiming him a genius. He gets on school bully Murph's bad side when he tapes him to the chalkboard. He retaliates by trying to drop the school's satellite dish on Junior, but it misses him and hits Ben instead, knocking him out. When Ben comes to, he sees the school nurse, Annie Young, and becomes smitten with her. Junior, annoyed at Ben's sudden love interest, retaliates by attempting to draw a mustache on Annie's picture hanging in the hall, only to be foiled by Trixie, the girl whose balloon he popped earlier. Throughout the film, they engage in an escalating prank war.
