Bronco is waiting on the U.S.A. side of the Rio Grande as Count Jacques da Tremaine rows a beautiful woman and a young boy across while being chased by three Mexican men in a second boat. When he sees the woman and boy being shot at, he fires to give them time to come ashore. He has a buckboard waiting for them. The Mexicans make the U.S.A. side themselves and continue firing at Bronco and the others. Luckily, Sheriff Lacey, nearby, comes up behind the Mexicans and disarms them. The leader of the Mexicans, Juan Rodriguez, says he has a warrant for the couple in Mexico but Sheriff Lacey says it is not valid in the U.S.A. Watching this from a nearby hilltop is Josh Glendon. Bronco takes the woman, Duchess Eugenia, and her ward, Prince Philip, to shelter at the ranch of Mrs. Kelly, a widow. He is astonished to learn that the boy is the son of the late Emperor of Mexico. Glendon who knows Lacey from earlier days and Rodriguez are all after the pair but for different reasons.
