Texas Ranger Jake Nelson patrols the U.S.-Mexico border, protecting the settlers from cattle rustlers, outlaws, and bandits. Sparks fly when Manuel Diego stirs up a revolt against the government, which leads to the murder of a newspaperman, who is the son of a U.S. senator, and the kidnapping of his sister, Elizabeth Madison, a journalist in the making.
With Elizabeth's photograph in hand--a dark-haired beauty with smiling eyes--Jake rides over the border to find her. After the Rangers defeat the marauders and rescue Elizabeth, Jake is surprised to learn she's not the spoiled daughter of a senator that he was expecting. In fact, he finds himself taken by her. And she by him.
