Summer Delgado is a junior in high school. Summer and her three friends Zoe, Ava, and Emma are excited about their cheer squad going to a national cheer tournament in Las Vegas. But the practice right before the trip, Summer has an "accident" in her pants. Because of that, Summer's mom and her cheer coach decided that Summer would have to wear diapers while on the trip. Summer is unhappy but reluctantly agrees since diapers would be way less embarrassing than waking up daily with a wet bed. Summer hopes she won't have any problems, but when her bully, Regina, and her three minions Amber, Olivia, and Natalia hear the news, they stride their way to expose Summer's problem. Will Summer win the battle, or will the four bullies win the war?
