There’s a war brewing in America, one simmering just below the surface but ready to explode. Captain Daniel Ash, his family, and the other 56 residents of Baker Flats military base find themselves at ground zero of that war one horrible night when hell descends upon their little corner of the world.
Awakened by a cry from his daughter, Ash goes to her room expecting to find her upset from a nightmare. Instead, he finds the girl burning with a dangerously high fever. As he struggles to get her into a cold tub he calls out to his wife for assistance, but gets no response.
Leaving his daughter in the slowly filling tub he returns to his bedroom and finds his wife still in bed. Dead. Panic now flooding in, Ash races to his son’s room and finds him apparently unaffected by whatever killed his wife and has made his daughter dangerously ill.
As he huddles in the bathroom with his two children Ash makes a frantic call to 911 pleading for help, but when it finally arrives it is not what Ash had expected, and his life will never be the same again.
