Consider another 1920: Imperial Germany has become the most powerful nation in the world. In 1914, she had crushed England, France, and Russia in a war that was short but entirely devastating.
By 1920, Kaiser Wilhelm II is looking for new lands to devour. The United States is fast becoming an economic super‑power and the only nation that can conceivably threaten Germany. The U.S. is militarily inept, however, and is led by a sick and delusional president who wanted to avoid war at any price. Thus, Germany is able to ship a huge army to Mexico to support a puppet government.
Her real goal: the invasion and permanent conquest of California and Texas.
America desperately resists as the mightiest and most brutal army in the world in a battle fought on land, at sea, and in the air as enemy armies savagely marched up on California, and move north towards a second Battle of the Alamo. Only the indominable spirit of freedom can answer the Kaiser's challenge.
