On the surface, the mountain town of Engelstatt, Austria is picture-perfect. It offers guests stunning views, fresh air, and the chance to experience an Alpine village untouched by time. For university student Jacob Liro, a school shooting survivor and aspiring artist, it is the perfect place to spend spring break with his classmates and a chance to hit the reset button on his life. What Jacob and his class don’t know is that beneath its fairy-tale facade, something sinister lies in wait in the salt mines below the town — and horrors from Engelstatt’s Nazi past threaten not only their lives and their sanity, but the entire world.
