The true story of Sir Nicholas ‘Nicky’ Winton, a young London broker who visited Prague in December 1938. He found families who had fled the rise of the Nazis in Germany and Austria, living in desperate conditions with little or no shelter and food, and under threat of Nazi invasion. How many children could he and the team rescue before the borders closed? Fifty years later, Nicky is still blaming himself for not doing more. It’s not until a live BBC Television show, ‘That’s Life’, surprises him by introducing him to some surviving children – now adults – that he finally begins to come to terms with the guilt and grief he had carried for five decades.
