Jiří and Jan are two Czech soldiers, fighting alongside the Allied forces against the Italians during World War II in Tobruk, Libya. Jiří Pospichal, 18 years old, signs up as a volunteer in the Czechoslovak 11th Infantry Battalion. His naive ideas about heroism are rawly confronted with the hell of the African desert, complicated relationships in his unit and the ubiquitous threat of death. All this takes its cruel toll in the shape of his gradual loss of self-respect and courage.
