What choice do you have if you are badly injured in the desert and a gunslinger finds you? Rango promises to do everything if Jake brings him to town. Jake agrees, but the price is high, which Rango has to pay.
When Rango wakes up in a stormy night because of shots outside of the town, he finds Bill unconsciously in the desert. But shortly after that, Bill disappears. Nobody cares but Rango can't forget a question: Is Bill dead or still alive?
