Cowboy and Indian are leaving on a luxury cruise, but they've got caught up. They have totally forgotten that today is back to school day! Goodbye tropical islands, our friends desperately find themselves on the school benches being put through the monotony of class. To liven the start of the school year up and to welcome the new geography teacher, the head teacher organises a big contest. The laureates will get to spend a day on the Moon together with M. Youri. Cowboy and Indian are of course ready to do everything to win.
