Plot line: Set against the backdrop of the greatest clandestine race against time in the history of science with the mission to build the world's first atomic bomb in Los Alamos, New Mexico. Flawed scientists and their families attempt to co-exist in a world where secrets and lies infiltrate every aspect of their lives.
I find this behind the scenes look at the men and women at Los Alamos fascinating. My only complaint is that the show seems to shy away from the science and math, which leads to a sort of dumbing down that loses much of the punch of what was happening with nuclear physics at the time. Without that it does seem rather like another show about human dynamics and drama against that particular backdrop, but I'm still hooked.
You can see the season trailer here. If you have yet to see it, this is a TV series worth watching.
