As school lets out, Spanky and Alfalfa send Buckwheat and Porky back into the building to deposit a phony doctor's note on the teacher's desk, so that they can skip school the next day and go to the circus. As the teacher's leaving, she tells the boys that she's taking the whole class to the circus. When they run back to the building to retrieve the notes, the little kids are just closing the doors, which are now locked. They show up that night to break into the school and get the note back. Stormy weather, a power outage, and various other spooky happenings, send all four boys - and the janitor - running for their lives.
