During World War II, Lt. Joe Costa leads a weary platoon in the European theater, confronting not only enemy forces but also internal conflicts that threaten their mission. Frustration mounts as Costa repeatedly clashes with his cowardly superior, Capt. Erskine Cooney, whose lack of leadership jeopardizes their safety. Cooney's favoritism toward certain soldiers and refusal to take decisive action in critical moments create a perilous environment for the entire unit. Costa’s repeated attempts to seek intervention from higher command fall on deaf ears, thereby straining his patience and increasing tension within the ranks.

As the platoon progresses toward a crucial objective, the consequences of Cooney’s incompetence become dire. The relationship between Costa and Cooney deteriorates further when another poorly executed order leads to unnecessary casualties. This mounting friction reaches a boiling point, driving Costa to confront his commanding officer directly. Amidst the chaos and battle pressures, the soldiers wrestle with their loyalty to the chain of command and their instinct for self-preservation. The film examines themes of leadership, courage, and moral responsibility in the harrowing context of war.
