On his first day as a fourth-grader, Sune is welcomed by an unwanted surprise.
A new boy is in Sune's seat and he's everything Sune wants to be. Not only that, but his name is also Sune. It's the worst possible start to the fourth grade. Pretty soon, Sune wants to out-do Sune in being cool. Not only that, Mom and Dad have their own one-up-manship issues. Only by accepting who they all are can they just chill out and be friends at the end.
