Theodore Taylor was one of the most brilliant engineers of the nuclear age, but in his later years he became concerned with the possibility of an individual being able to construct a weapon of mass destruction on their own. McPhee tours American nuclear institutions with Taylor and shows us how close we are to terrorist attacks employing homemade nuclear weaponry.
