The school year is finally over, and T.J. Detweiler is looking forward to a fun-filled summer. Boredom quickly sets in, until T.J. uncovers a scheme to do away with summer vacation! Former principal Dr. Benedict, who once tried to eliminate recess from the school day, now plans to use a laser beam to alter the weather and create permanent winter. It sure would be tough to have to go to school year-round, so T.J. calls in all his friends for help. Just when the kids appear to be facing their final test of strength against the mad principal, the faculty joins together to help save summer vacation.
