Hoppy finds a wounded girl and later finds Judge Morton who claims the girl is his daughter and he is looking for her. But Hoppy soon learns the girl is looking for stolen gold she wants to return and the Judge in not her father but only wants the gold. Hoppy and the girl find the gold but the Judge and his men find Hoppy and the boys and trap them in a cabin.
A rather energetic and unusual mix of mystery and treasure hunt with plenty of chase sequences, night riding and Alabama Hills adding to the atmosphere. But it's the serpentine plot and the interesting characters that make this film, especially the card playing sheriff, who must be the most useless sheriff ever. It's amazing that Hoppy didn't slap him in the face. Just comes to show how he respects a lawman, no matter how thick he is.
