1939: fascism spreads across Europe, Franco marches on Barcelona and two German chemists discover the processes of atomic fission. In Berkeley, California, theoretical physicists recognise the horrendous potential of this new a weapon that draws its power from the very building blocks of the universe. Struggling to cast off his radical past and thrust into a position of power and authority, the charismatic J Robert Oppenheimer races to win the 'battle of the laboratories' and create a weapon so devastating that it would bring about an end not just to the Second World War but to all war. Tom Morton-Smith's new play takes us into the heart of the Manhattan Project, revealing the personal cost of making history.
