Raoul Wallenberg, the diplomat and scion of Sweden’s powerful Wallenberg banking dynasty, saved tens of thousands of Hungarian Jews during the Holocaust. By issuing protective passports and establishing safe houses he became one of the greatest humanitarian figures of the 20th century. But after being taken into Soviet custody in 1945, Wallenberg vanished without explanation. For the first time, this gripping documentary uncovers the chilling fate of a man who saved a generation, yet tragically could not save himself.
