Mail-order bride Lindy O'Hara and her Texas Ranger/rancher husband Cal Bronson are immediately attracted to each other and form a passionate bond, but he doesn't trust her enough to tell her about the case he's supposedly working on. When she finds a diagram of the inside of a bank in his study and spies him in a clandestine meeting with an unsavory character, she hopes for the best but fears the worst. Is her brave and kind husband actually a bank robber, or is he an honorable lawman working undercover? One way or the other, Lindy is determined to keep him safe by showing up at the allotted time to foil the robbery. What could possibly go wrong?
