The gang's back for a very special summer at the Hills: the camp's fiftieth anniversary! Wiener is especially excited to be back. His little brother, Max, is finally coming to camp, and Wiener can't wait to show him the ropes (and show him what a cool big brother he is). Unfortunately, it doesn't take Max long to realize that Wiener isn't exactly the Camp Legend he made himself out to be.
