Davy isn't sure he's ready for school. He's heard about mean teachers and bullies. Sizing up some potential classmates, he simply decides not to go. He has a better idea: he will build his own school. Not only that, he will put wheels on it!

One thing leads to another, and Davy's mobile school goes out of control, landing in the middle of the classroom of the very surprised and none too pleased Mr. Stern. Davy is relegated to the corner until recess. Then, all the kids gather around him to find out how to put wheels on their school. Trouble looms for Mr. Stern!
