In the picturesque Bavarian town of Oberammergau, two friends, Markus and Thomas, are using the instructions found in an old Jewish diary to gain access to a WWII underground military base formerly codenamed: CERUSIT. Used by the Nazis as a secret research institute, there are shrouded rumors to this day about the lost gold of the Third Reich. The entrance to the cave system, however, lies right within the restricted area of a U.S. military base.
