A Compassionate Spy

Physicist Ted Hall is recruited to join the Manhattan Project as a teenager and goes to Los Alamos with no idea what he'll be working on. When he learns the true nature of the weapon being designed, he fears the post-war risk of a nuclear holocaust and begins to pass significant information to the Soviet Union.
