Brock Masters (Mark Roberts) has been awarded a contract to supply the army with horses.  Corrupt businessman Grat Hanlon (Clayton Moore) wants that contract for himself so he sends his henchmen to kill Brock.  Because Brock has no known relatives, Grat believes that both the horses and the contract will soon be his.

However, Brock does have an heir!  He adopted an Indian child named Johnny (Louis Lettieri).  Johnny inherits the contract and both the Durango Kid (Charles Starrett) and Smiley Burnett are going to make sure that Johnny is able to deliver the horses.  Smiley is also going to find some time to sing some songs that have even less to do with the story than usual.

Cyclone Fury was one of the later entries in the Durango Kid series.  By the time it was made, Colombia was no longer willing to spend much money on the series so that majority of the film’s action scenes are lifted from other Durango Kid movies.  If you’ve never seen another Durango Kid movie, the action scenes are exciting and feature some impressive stunts.  If you have seen another Durango Kid movie, this one is going to seem really familiar.

For western fans, the main appeal here will be seeing Clayton Moore playing a bad guy.  Moore had already played The Lone Ranger when he appeared in this movie.  At the time Cyclone Fury was made, Moore had been unceremoniously fired from his most famous role and The Lone Ranger was being played by John Hart.  Hart would only last a season and Moore would subsequently be invited back to play the role that defined his career.  As for Cyclone Fury, Moore is convincing as Grat, though the character himself is just a typical Durango Kid bad guy.  The Durango Kid was always going up against seemingly respectable businessmen who were actually outlaws.

One final note: Moore’s Lone Ranger co-star, Jay Silverheels, appears in this film but only in archival footage from an early adventure of The Durango Kid.
