Rango is a pet chameleon always on the lookout for action and adventure, except the fake kind, where he directs it and acts in it. After a car accident, he winds up in an old western town called Dirt. What this town needs the most is water, but they also need a hero and a sheriff. The thirsty Rango instantly takes on the role of both and selfishly agrees to take on the case of their missing water.

The Ultimate Western Spoof. A town where everyone seems to be named Johnson is in the way of the railroad. In order to grab their land, Hedley Lemar, a politically connected nasty person, sends in his henchmen to make the town unlivable. After the sheriff is killed, the town demands a new sheriff from the Governor. Hedley convinces him to send the town the first Black sheriff in the west. Bart is a sophisticated urbanite who will have some difficulty winning over the townspeople.
