Gelman, the resident school bully, begins to pick on Gus because the student who he previously bullied, Stemple, moves away, and, unaware that Gelman was around, Gus exited the bathroom. After turning his attention to Gus, Gelman routinely tosses Gus into a garbage bin, despite the gang's best attempts to thwart Gelman and despite Miss Finster threatening to bring him down to Principal Prickly's office faster than he can say "detention" if he touches Gus or any other kid on her playground (he immediately ignores her).
After receiving some conflicting advice from Mikey and Spinelli, both of whom disagree with each other on what to do, Gus asks his dad what a "little country," namely Gus, should do about being picked on by a "big country", namely Gelman, and Gus' dad tells him the story of Belgium and Germany during WWI. This inspires Gus to stand up to Gelman, for which he gets a serious beating. However, at the end of the battle Gus' friends and many of the kids at Third Street step in to help Gus win the war, quite typical of the story of WWI.
