In 2018, a mission to the dark side of the Moon unveils an astonishing discovery: a secret Nazi space program, hidden since World War II. The Nazis have built a formidable base called Schwarze Sonne, complete with a fleet of spacecraft, and they have been biding their time to launch an invasion back on Earth. The base is populated by descendants of the original Nazi scientists and soldiers who fled there in 1945. When American astronaut James Washington stumbles upon the base, he is captured and becomes a part of the Nazis' diabolical plan. Washington’s smartphone, with its advanced computing technology, becomes the last piece the Moon Nazis need to complete their power source and begin the invasion.

The Nazi leaders, including the zealous Adler and the idealistic Richter, see the phone as a sign that Earth is now ripe for conquest. As they prepare their moon base for a full-scale assault on Earth, Washington is forcibly "Aryanized" to assist but seeks to subvert their plans from within. Back on Earth, an opportunistic U.S. President is advised by her campaign manager Vivian Wagner and sees the militaristic potential of the Nazi's technology, aiming to use the conflict to boost her own political standing. With the threat of the Fourth Reich initiating a new global conflict, Earth's fate hangs in the balance as ideological and extraterrestrial tensions rise.
