Yohay Jan Remetz was born and raised in pre-WWII Warsaw. Upon the German invasion into Poland he was locked up in the Warsaw ghetto with his family, struggling to sustain daily under the brutal Nazi occupation. Determined to survive, he fled the ghetto, and with endless bravery and wit, took on a Christian identity which eventually led him to work as a German airfield-guard. Under this fake identity he later joined the Polish resistance movement against the Nazis, thereby fulfilling the last two commands of his deceased aunt: survive and avenge.
