Caught between Washington's military pressure, his love for scientist Anna Weiss, and his ancestral powers of second sight, the decision to guard or sabotage the programme casts Joe Pena in a critical role at the dawn of the Nuclear Age. In a New Mexico blizzard, four men cross a barbed-wire fence at Stallion Gate to select a test site for the first atomic weapon. They are Oppenheimer the physicist, Groves the general, Fuchs the spy. The fourth man is Sergeant Joe Pena, a hero, informer, fighter and musician. These four men - and a cast of soldiers, roughnecks and scientists - will change history forever.
