When friends join ex-soldier Jonah on a European vacation, they discover that the beautiful German town where he was once stationed is completely vacant.
The strangeness doesn't end there. One of their group falls into a coma, another sees a strange creature, and large mounds of dirt appear everywhere.
Before they can determine what is happening, Jonah realizes something deadly is watching from the shadows, waiting to hunt.
But what they stumble across in the depths of an abandoned military base threatens not only their lives, but all of mankind.
