During World War II, Brazil was an ally of the United States, England and France. At the time there were directed over 25 thousand soldiers from the BEF (Brazilian Expeditionary Force) to fight the enemies, represented by the Axis: Germany, Italy and Japan. Almost all soldiers came from poor backgrounds, and were mostly unprepared for combat, they had to learn in practice to fight for survival. After suffering a collective panic attack at the foot of Castle Hill, the soldiers Guimarães (Daniel de Oliveira), Tenente (Julio Andrade), Piauí (Gaspar Francisco) and Laurindo (Thogum) try to get down the mountain, but end up missing the others. When they were reunited, they had to decide to return to the battalion and are at risk of facing court-martial for dereliction of duty, or return to the position the night before and at risk of facing a surprise attack of the enemy. That's when the journalist Rui (Ivo Canelas), tells about an active minefield and they think this is a chance to redeem the mistake they committed, but much is yet to happen and the war is far from over.
