Blaze Derringer is a Texas cattle baron's son. He goes to a cabaret on his birthday, helps a pretty young woman and her guardian avoid a raid, but gets tossed from college for bad behavior. His disgusted father dispatches him to seek his fortune. Blaze jumps a freight, befriends a fake British duke and a sporting African-American, and is offered a prize fight in Galveston. He wins, but may have killed his opponent, so he takes the offer of the woman from the cabaret to accompany her to Begonia, where she's a princess about to be crowned. A court minister, the dastardly Count Verensky, has plans to share the throne and her affections. Can the plucky American help the Europeans sort things out?
