Following Holland's fall to Hitler's army, Diet Eman's Jewish friend Herman was told to report for transport. Upon hearing this, she and her fiance, Hein Sietsma, made the decision to risk their lives for their beliefs. Diet and Hein would later be sent to concentration camps for their acts of resistance, and Hein would indeed lose his life. Diet survived. She came to the United States and made her home in Michigan following the war, and she began to tell her story. The author James Schaap happened to be one of her listeners, and, taken by her story, offered to be her biographer.
