Smugglers are trying to smuggle stolen paintings from Europe into So. America for a million dollars. Senorita Rio has discovered the plot, but the smugglers are onto her. A fake death of a Rio look alike is planned at a public restaurant where the real Senorita R. is dining, and in the confusion at the restaurant, bandits kidnap the real Senorita Rio and take her to their hideaway to interrogate her, believing that she knows something about their plot. In the process, she is tied up, arm carried, put in chair bondage, and later clamped to a dungeon wall. She eventually escapes and attempts to return to capture the criminals. She finds a large machine gun, and in self defense a shoot out begins and she kills all the bad guys. She was one of the big guns in Fiction House's great good girl arsenal, and inspired many a WW II GI lounging in a European foxhole looking for something to cure their anxiety and free-time boredom.
