Before Arthur knows it, he's dragged into the Tough Customers after Buster brags about him being the "world's greatest gleeper." He and Buster didn't even know that "gleep" is a slang term for stealing, but they didn't want Arthur to look stupid in front of this tough group. Pretty soon, gossip gets around the entire school about Arthur being a thief, causing him some newfound popularity, but also to lose some friends. Then, he faces a trial that could change things for him forever, or restore what he lost. (thetvdb.com)
