Defiance (2009)

The year is 1941 and the Jews of Eastern Europe are being massacred by the thousands. Managing to escape certain death, three brothers take refuge in the dense surrounding woods they have known since childhood. There they begin their desperate battle against the Nazis. The brothers turn a primitive struggle to survive into something far more consequential - a way to avenge the deaths of their loved ones by saving thousands of others.
