This is a George O'Brien Western that doesn't fit the George O'Brien Western model I have built. He does not play an undercover lawman. Instead, he is a cattle rancher who ends up with a tungsten mine on his land. Maybe I'm just getting used to these budget Westerns or maybe this one was particularly well done, but I was pretty caught up in the suspense scenes at the end. One involved a runaway mule train pulling loads of tungsten ore beside a precipice, and another involved fist fights while a fuse burned toward a pile of dynamite. Ray Whitley does the singing, as usual.
