Cammy, an old adversary of Gary's, is posted to the barracks and old rivalries are soon restored in the form of a brawl. Sergeant Thomson punishes them both but a series of tit for tat exchanges follow. Things quickly get out of hand when army property is defaced and Gary is the one blamed. With the boys unable to provide an alibi and Thomson refusing to believe that Cammy is to blame, Gary finds himself in serious danger of being kicked out of the army forever.
