A class trip is canceled due to budgetary reasons, so the students devise a plan to fight back; Uncle Will, Dusty, Chance and Herman turn a mall upside down for a special presentation to prank a security guard.
Chance, Herman and Dusty become mesmerized by a new dinosaur virtual reality game at school and it inspires the next set of pranks that include Bailey disguised as a mind-melding robot from the future and a stunt that leaves an unsuspecting camp counselor believing he has discovered a real spaceship in the woods.
The crew pulls an all-nighter at Uncle Will's to edit the pranks and upload them to their channel before a morning deadline. Meanwhile, Herman poses as a kid who thinks he's a medieval knight and convinces his babysitter to do whatever he says.
Uncle Will is unknowingly set up on a blind date with Bailey's mom. Meanwhile, a target is hired to be on-air talent for a home shopping network owned by Chance's dad, which causes Chance to have a live on-camera meltdown.
Herman tries to pull a prank on his own and ends up in the school's trophy case. Meanwhile, Chance and Dusty accidentally turn on a high-tech laser security system in their dad's archeology lab that has extra "security" reinforcement.
