After crooks pull off a bloody robbery at the Mexican border, a U.S. agent poses as an Asian jewel buyer so he can investigate the gang of smugglers.

When he gets a call for help from his former sweetheart, Hoppy and his crew ride out to challenge a group of cattle rustlers harassing the ranchers.

Hopalong Cassidy and the rangers create a setup to cast him out as an outlaw in order to lead a crooked gang whose leader is hiding in plain sight.
