The Beginning or the End

In 1945, physicist and atomic scientist Dr. J. Robert Oppenheimer (Hume Cronyn) praises the discovery of atomic energy, but also warns of its dangers. American scientists such as Matt Cochran (Tom Drake), working under the guidance of Dr. Enrico Fermi (Joseph Calleia) and Dr. Marré (Victor Francen), have split the atom, and essentially beaten the Germans in the race to create an atomic bomb. With the assistance of Albert Einstein (Ludwig Stössel), they inform President of the United States Franklin D. Roosevelt (Godfrey Tearle) that a monumental discovery has been made.
