Andie and the Alien

"Over 500 years ago, an alien spaceship crashed in the undiscovered Americas. Rescued by the local natives, the alien promised to protect them by placing a force-field over the Americas -- preventing exploration and colonization of their land -- and altering the course of history as we know it forever. 500 years later, in a world without the United States of America, the Nazis have won World War II and rule absolutely. Until one day, a captured British scientist named Andie, with the help of Albert Einstein (of course!), hatch a plan to rescue the alien and save the future from the Third Reich."
