TJ Detweiler and his five best friends Vince LaSalle, Ashley Spinelli, Gretchen Grundler, Mikey Blumberg and Gus Griswald have finally at long last finished 4th grade at 3rd Street School. But boredom quickly sets in when TJ's friends leave for camp until T.J. uncovers an evil plot to do away with summer vacation! A crazy former principal, Dr. Benedict, is planning to use a laser beam that he stole from the US Military Base to alter the weather and create permanent winter! Naturally, TJ rallies his friends together and they conspire to fight the wicked Dr. Benedict. But it turns out that Dr. Benedict is so strict that he wants to change the orbit of the moon in order to put the nation in a constant freeze, thus putting an end to summer and creating a year-round school year! It's up to only them to save the world for kids all over the world.

Mrs. Finster:
Hey, teacher! Leave them kids alone!
