Fireball is having a good time taking part in some reenactments by the local War Games Club, using tanks and such restored from scrapyard junk. One is a German Tiger and it almost ran over Fireball and the club leader. When Fireball learns the tank has been stolen, he is off to get it back and learn why. What he discovers is the involvement of his old enemy, Reburg.
