It's the most exciting time of year at Third Street Elementary, the last day of school. But boredom quickly sets in for protagonist T.J. Detweiler as his five best friends are heading for summer camp. One day, while passing by the school on his bike, he notices a green glow coming from the auditorium. This is the work of the insidious former principal Dr. Phillium Benedict and his henchmen. He is planning to get rid of summer vacation using his newly acquired Tractor Beam, which he stole from the US Military Base in an effort to raise US Test Scores, and it's up to the T.J. and the gang to stop him. In the end, they, with the help from the other students, Principal Prickly, Ms. Finster, and the other teachers, destroy the laser, Benedict and his henchmen are arrested, and T.J.'s best friends decide to spend their summer with him.
