WW2. 1943. The Thule Society and the Third Reich explore areas around Tibet for access into the underground tunnel systems that lead to Agartha and the other civilizations living within the earths crust. The secretive SS Division known as the Ahenerbe continue to conduct their expeditions in the mountains all around the region. They know that there is a secret order of monks who protect the entrance into the underground tunnel systems that lead into Inner earth. Their search to find them continues.
The Special Operations Executive (British Intelligence) learns that the Nazis are in the Himalayas searching for something of great importance and put a climbing team together led by a New Zealand female by the name of Mere Dargaville. At a great danger to herself, and to the rest of the team they venture into the mountains risking everything to discover what is so important to their enemy.
With the help of the Nepalese Sherpas and Ghurka soldiers, SOE Agent Mere Dargaville locates the cave system and sends down a team of explorers to navigate it. The big problem is that they do not return. Neither do the Nazis who seem to have left everything on the surface abandoned. It's all a big mystery to Agent Dargaville as she tries to figure out what's going on.
