Colonel William Ryan, a ranch owner, in the Lone Star State, has named his only daughter Texas. Jack Parker, a devil-may-care cowpuncher, loves only two things, one is his horse and the other a photograph of Texas Ryan, whom he has never seen. He has named his horse "Dream Girl" after the girl of the photograph. After several years in an eastern college, Texas return home. Her father is happy and she is idolized by the cowboys of the ranch. Antonio Moreno is the head of a band of cattle rustlers. His lieutenant, "Dice" McAllister, a former road agent, uses his office as marshal as a cloak for unlawful deeds. Moreno and McAllister have long plotted to secure Ryan's wealth, and Moreno resolves to pay court to the girl. In the "Last Chance" saloon and dance hall a shooting scrape occurs. Jack Parker, enemy of McAllister, is charged as being an accessory.
