It's 1946. Mankind has just gone through one of the most brutal wars it ever faced. While the rest of the world is still in shock and trying to find ways to prevent such an event from ever taking place again, a Jewish/German scientist decides to act.

With a device he was engineering for the US government, he travels back into time to kill the person who he sees as the root of all misery; Adolf Hitler. He catches up with Hitler in 1926, as Hitler is still a young - but already embittered - man and 'disposes' of him. Without thinking through the consequences thoroughly enough, as will soon turn out.

Without Hitler and Nazi-Germany to keep the him in check after all, Hitler died before he ever became of any importance, Stalin takes his communistic USSR to unknown heights and then decides to speed up the world-wide Marxist revolution a bit by invading the free countries of Western Europe. Obviously, the West-European countries aren't too pleased with this and starts a grim guerilla war against the Russian invaders.

And so, in spite of our dearest scientists efforts, a new World War starts.
