Antychryst

Four boys act out games in a nearly barren landscape near a mining excavation where blasting is going on. The oldest, Szafran, is their leader. When he gets into a frenzy, so do the others: running barefoot through thistles, rubbing dirt in their hair, catching fish barehanded. Szafran says he is the Antichrist and gives orders. Are these games or something else?
