Concentration camp commander Kraft finds out that prisoner Kominek is a former professional boxer. Overnight, the prisoner is made Kraft's exercise partner and unwillingly rises to a privileged position at the camp. His anger over the death of his friend and co-prisoner leads to open revolt. The film brings a new view of human degradation during fascism by a tragic story of one man whose only chance for survival is to accept the rules of an unequal game.
