On July 21 2012, in the mountains of the Emporda county, near the Spanish border with France, an Archaeology PhD student and three friends, go into a bunker searching for pieces of art supposedly stolen by the Nazis. However, when they open a secret chamber, they only find a few piles of dusty boxes containing small tablets of Panzer Chocolate; which was widely distributed among German soldiers in the 1940’s. Soon, the peaceful lives of the four unlucky friends turn into a scary nightmare, and they find themselves running for their lives.
