The narrative follows a circle of school friends who serve together and endure rain-soaked, mud-choked camps while awaiting and then joining a major offensive. It moves from prebattle preparations and small moments of comradeship into intense combat episodes—artillery barrages, raids on enemy positions, fighting in woods and towns, spying, capture, and an underwater struggle—alongside personal losses and acts of vengeance. Scenes alternate action with periods of rest and recovery, concluding with reflection on the scope of the fighting and the rewards and recognition earned by the unit.
