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. But the Mexicans won't give up that easily, as Elizabeth becomes the target of an all-out hunt. Leaving Elizabeth back at Fort Williams, Jake and his men set off again, this time to go after Diego himself--to apprehend him and his renegades and bring them all to justice. Meanwhile, Jake knows what's begun between him and Elizabeth is undeniable. Amid all the turmoil, Jake finally admits how much he loves her. She tells him the same. Until now, they've lived in different worlds, yet it is those differences that drew them together.
