In the sum­mer of 1940, the Nazis con­fined 400,000 Jews inside a small area in War­saw, cut­ting them off from the out­side world. Erik Cohen, an elder­ly psy­chi­a­trist, must move into the tiny apart­ment that his niece shares with her son, Adam. Erik adores his great-nephew, but he some­times has trou­ble relat­ing to him. As the war inten­si­fies, dai­ly life becomes more dif­fi­cult and under­ground resis­tance and smug­gling become nec­es­sary for sur­vival. When Adam goes miss­ing on a cold win­ter day, Erik search­es for him. When his muti­lat­ed body is dis­cov­ered and anoth­er mur­dered child turns up, Erik and his friend Izzy decide to find out who is respon­si­ble for the deaths. Is there a Jew­ish trai­tor in their midst? This mov­ing his­tor­i­cal thriller por­trays a man who los­es every­thing that is impor­tant to him. Rather than giv­ing in to despair, he fights to make sure that those who are lost will be remembered.
