It's Miles' and Niles' final year at Yawnee Valley Science and Letters Academy, and the Terrible Two have one goal: an epic prank. Something big, something brilliant, something that will leave a lasting legacy at their school. It should be easy-peasy for these experts, especially now that their principal has gone from archnemesis to pranking protege. But their smooth sailing gets downright bumpy when they find out that the new superintendent is none other than Bertrand Barkin, their principal's father...and their sworn enemy.
