When young Richard Gale arrived in the Southwestern border town of Casita, he didn’t realize it was a tinderbox waiting to explode. There’s a revolution in Mexico and American troops are stationed along the border. The town itself is overrun by bandits and renegades. And things only get worse for Gale when he promises to help protect the daughter of a murdered Spanish aristocrat. The bandit leader who killed the girl’s father wants her found—right away—and he’ll destroy anyone who tries to stop him.
