Jessi's new teacher Mr Trout is . . . different. All the kids at SMS laugh at him because he's shy and wears odd clothes. Jessi know it isn't right. But the jokes the kids play on Mr Trout are funny.
So when Jessi is asked to play a prank - a big one - on Mr Trout she goes along with it. After all, no one else thinks it's mean.
Except Mr Trout. And now Jessi has to live with the horrible thing she's done.
