Who Killed The Man On The White Horse?

Cowboy movie star Clayton Steele is grand marshall at the rodeo, but in the final parade, he rides into the arena, already dead, his neck broken. Burke questions his megalomaniac rival, his former stunt man, his ""Indian"" sidekick, a sexy veterinarian, and a vindictive lady bronc buster, in order to find out who sent Steele to that Great Corral in the Sky. A well-trained horse provides a vital clue. Before he can arrest the killer, Burke almost has his own neck snapped!
