Continuing to observe cruelty, Irwin attempts to unify the prisoners by building a "castle wall" of stone and mortar at the facility, which resembles a medieval castle in many ways. Envying the respect Irwin is clearly receiving, Winter orders his guards to destroy the wall. When Aguilar, an integral leader in the wall's construction, blocks the bulldozer, Winter orders sadistic sharpshooter Cpl. Zamorro to fire a normally non-lethal rubber bullet directly at his head, killing him.

Peretz places Winter under arrest for shooting Irwin. The prisoners, now standing again, begin to salute the flag. Astonishingly, Winter notices that Irwin has actually raised the flag right-side-up, meaning that he had shot Irwin fruitlessly. The flag flies above the prison's walls as General Wheeler arrives. Colonel Winter is led away in handcuffs. The inmates build a new wall as a memorial to their fallen comrades. Aguilar and Irwin's names are among those carved onto the castle wall.
