When Herman tries to do a prank on his own, he ends up trapped inside the school's trophy case. Now it's up to the rest of the gang to get him out without getting caught. Meanwhile, when Chance and Dusty show the babysitter their dad's archeology lab, they accidently turn on a high-tech laser security system with extra "security" reinforcement.

Facing a morning deadline, the crew pulls an all-nighter at Uncle Will's to edit the pranks and upload them to their channel in time. Meanwhile, Herman poses as a kid who thinks he's a medieval knight and convinces his babysitter to do whatever he says like acting like a court jester and fencing. It's all fun and games until an unexpected guest shows up for a battle.
