Prague, 1938. As the city teeters on the brink of Nazi occupation, a London banker does everything in his power to save hundreds of children facing certain death in concentration camps. At great personal risk, Nicholas Winton organizes convoys to England, where 669 Jewish children find refuge. This true story, hidden for decades, is revealed to the world when, in 1988, a British television program invites Nicholas to share his story. Little does he know that the audience includes the children—now adults—who survived thanks to him.
