During World War II, there were mounting fears that Hitler was building an atomic bomb. Such a prospect depended on two of the world’s top nuclear scientists: brilliant German physicist Werner Heisenberg, and his Danish mentor, Niels Bohr. In 1941, Heisenberg traveled 200 miles in secret to Copenhagen to meet Bohr.

The meeting put both men in immense risk, and had a cataclysmic effect on their relationship. This film was made with access to their personal correspondence and newly released documents kept secret for half a century.

Copenhagen Fall Out explores Heisenberg’s visit to Denmark and what happened during the pivotal meeting that was to become a defining moment of the nuclear age.
