The small mining town of Bataille, Missouri has been cordoned off from the outside world for six months. The inhabitants have no idea why. All they know is that ever since the so-called "Contingency," planes no longer fly overhead, strange creatures have been glimpsed beyond the perimeter, and large mechanical towers will gun down anyone who tries to escape. As Sheriff Erika Wright searches for the truth, she must listen to the advice of a serial killer, mingle with extreme conspiracy theorists, and negotiate with vampires.
