In this melodrama, Captain Arthur Boyce (Alan Hale) encounters a pair of Mexicans at the border posing as brother (Edwin Cecil) and sister (Gretchen Hartman). They are really revolutionaries who have crossed into the U.S. to buy arms, but as they are dealing with Boyce, the woman, Juanita, realizes he was the soldier responsible for her brother being shot. She determines to have revenge on him, and later in California, they meet up again. Juanita manages to lure the captain away from his fiancee, Claire Nelson (Frances Burnham), but nevertheless, he turns down her advances. A murder occurs in the hotel room next to Juanita, and she takes the body and dresses it in her own clothes. It is believed that Juanita was killed and Boyce is held responsible for the crime. Meanwhile, Claire's guardian has been selling guns to the revolutionaries and he takes her down to Mexico. There Juanita captures them and prepares to have them executed. But back in California, the real murderer has confessed and Boyce crosses the border to save his sweetheart. Juanita suffers a fatal bullet wound and Boyce and Claire are reunited.
