Set against the backdrop of the greatest clandestine race against time in the history of science with the mission to build the worlds first atomic bomb in Los Alamos, New Mexico. Locked away in the worlds most secretive city, the scientists and their families surrender their freedoms, compromise their marriages, and even sacrifice their sanity to end one war and usher in another, the Cold War waiting just over the atomic horizon, all while embedded spies and a climate of paranoia threaten to destroy the project from within.
