George and Harold arrive at the same camp, but their hopes and dreams are cut short when Mr. Krupp (who is the camp director) splits the camp into Camp Lake Summer Camp (George) and Lake Summer Camp Camp (Harold) to afford an $80,000 LeisureMyLand inflatable private island. He puts a fence in between George and Harold, as he hopes to turn the boys against each other. When George and Harold make a comic without each other, war begins. Both camps create the Balloonatic and Camplifire, but when their advances go wrong, it's time for Captain Underpants!
