After turning out plutonium for the Cold War, the shuttered Hanford Nuclear Facility's poisoned buildings still pose a risk to the surrounding community. The men who guard the facility are told the dangers are under control, but then the worst happens --- a thunderous explosion in the dead of night.

Kieran Mullaney survives the blast, but his attempts to discover what really happened are met with silence and threats. Convinced that Hanford is hiding something, Kieran reconnects with his old friend, lawyer Emily Hart, and enlists her help in finding out the truth. But the deeper the two of them dig, the stranger --- and more dangerous --- this case gets.
