A Texas settler and his daughter, Sally, start on a journey in a prairie schooner after bidding farewell to Sally's mother and to Tom, the ranger, who is operating in the neighborhood on a lookout for cattle rustlers and illicit whiskey sellers. The great wagon is hauled out of the corral by a pair of spirited horses, while ranger Tom departs to take up the trail of a "bootlegger" who is reported to have been operating among the Indians thereabouts.
