Clay is in trouble again, this time for drawing a picture of the principal as a donkey. But Clay doesn't mind; he's proud to be a troublemaker, just like his older brother, Mitch. However, Mitch's temper got him sent to jail for two months, and now he wants Clay to stay on the straight and narrow. Clay promises Mitch he'll try, but it's really hard. His principal and teachers don't believe Clay is really trying to change, and his best friend and fellow troublemaker, Hank, isn't exactly supportive of his efforts. What's more, Clay's favorite prank-filled holiday, Halloween, is coming up! Can Clay really change his mischief-making ways once and for all?
