From the civil rights struggle in the United States to the Nazi crimes against humanity in Europe, there are more stories than people passing each other every day on the bustling streets of every crowded city. Only some survive to become history. Recently released from prison, Lamont Williams, an African American probationary janitor in a Manhattan hospital and father of a little girl he can't locate, strikes up an unlikely friendship with an elderly patient, a Holocaust survivor who had been a prisoner in Auschwitz-Birkenau. A few kilometres uptown, Australian historian Adam Zignelik, an untenured Columbia professor, finds both his career and his long-term romantic relationship falling apart. Emerging out of the depths of his own personal history, Adam sees, in a promising research topic suggested by an American World War II veteran, the beginnings of something that might just save him professionally and perhaps even personally. As these two men try to survive in early twenty-first-century New York, history comes to life in ways neither of them could have foreseen. Two very different paths - Lamont's and Adam's - lead to one greater story as The Street Sweeper, in dealing with memory, love, guilt, heroism, the extremes of racism and unexpected kindness, spans the twentieth century to the present, and spans the globe from New York to Melbourne, Chicago to Auschwitz.
