It’s the 1950s, and Zygmunt Schwarzer is on his way to an apartment in Manhattan, New York City, with an important delivery. He has with him the Second World War diary of a young Polish Jewess, Renia Stiegel. He delivers it to Renia’s sister Ariana and her mother Roza. Unable to face the diary, Roza puts it away unread. It would be decades before anyone could bring themselves to look at it.
