Trapped in a Polish ghetto with thousands of other Jews facing starvation or deportation to the death camps, Jacob is detained one evening at Gestapo headquarters. Eavesdropping, he overhears a radio report about a nearby Russian victory. At first he is silent, but circumstances compel him to pass on the good news of hope. In order to be believed, he feigns access to a hidden, strictly forbidden radio. Quickly he becomes a one-man bukwark against despair, a reluctant hero, but a tragic hero still - a man ultimately powerless to see or change the fate of his people.
