Tom Mix is on fine form as an undercover lawman, posing as a badman and even dressing up in a flashy Mexican outfit to romance the heroine. His mission is to infiltrate an outlaw gang and identify their mysterious mastermind. Tom and Tony pull off some good riding stunts, Fred Kohler provides excellent support as the surly heavy, and the photography is better than in some A movies. If you've never seen a Tom Mix sound Western, start with this one.
