Stanisław Zalewski spent 600 days captured in Nazi concentration camps. Like many other victims of Nazi terror, he remained silent about his pain for a long time. It was only after 40 years that he began to talk about it - at events, memorial services, and in schools. At the age of 99, he continues to do so to this day. For the first time, he tells his stirring life story as a deeply impressive ‘ambassador of remembrance’.
