In the Vilna Ghetto during World War II, Nazi Commandant Schoger demands that all children be sent to the death camp. When Abraham Lipman pleads with him to spare their lives, Schoger reconsiders, and tells Lipman there will be a chess match between himself and Lipman's only surviving son, Isaac, a chess prodigy. If Isaac wins, the children will live, but Isaac will die. If Isaac loses, the children will die, but Isaac will live. Only a draw will save the ghetto from this terrible predicament.
