Will Robie and Jessica Reel are two of the most lethal people alive. They're the ones the government calls in when the utmost secrecy is required to take out those who plot violence and mass destruction against the United States. And through every mission, one man has always had their backs: their handler, code-named Blue Man.
But now, Blue Man is missing.
Last seen in rural Colorado, Blue Man had taken a rare vacation to go fly fishing in his hometown when he disappeared off the grid. With no communications since, the team can't help but fear the worst.
Sent to investigate, Robie and Reel arrive in the small town of Grand to discover that it has its own share of problems. A stagnant local economy and a woefully understaffed police force have made this small community a magnet for crime, drugs, and a growing number of militant fringe groups.
But lying in wait in Grand is an even more insidious and sweeping threat, one that may shake the very foundations of America. And when Robie and Reel find themselves up against an adversary with superior firepower and a home-court advantage, they'll be lucky if they make it out alive, with or without Blue Man . . .
威爾．羅比以及潔西卡．雷爾是兩個極具危險性的人物。當有人策畫對美國發起暴動或大規模的毀滅，政府便會召集他們進行秘密行動。每一次出任務，他們的顧問──代號藍男，總會在幕後支援他們。
但現在，藍男失蹤了。
他最後的行蹤出現在科羅拉多州，藍男難得休假，他回到家鄉釣魚但卻突然消失，自那之後便杳無音信，團隊不禁害怕最壞的情況發生。
羅比及雷爾奉命調查藍男音信，他們來到格蘭地小鎮，發現鎮上有些問題。由於當地經濟停滯不前，又苦於警力欠缺，整個城鎮淪為犯罪、毒品以及激進暴力份子的聚集之地。
然而守在格蘭地將招致更危險、更可怕的威脅，甚至足以動搖美國的根基。當羅比和雷爾發現他們的對手擁有強大的火力以及主場優勢，不論能否找到藍男，他們若能活下來就算非常幸運了。
