Gun Fury is a 1953 3-D American Western film, directed by Raoul Walsh and starring Rock Hudson and Donna Reed, with major supporting roles for Philip Carey and Leo Gordon.
After a stagecoach holdup, Frank Slayton's notorious outlaw gang leave Ben Warren for dead and head off with his fiancée.
The other is Johash, an Indian with an equally personal grudge---his sister was abducted and murdered by Slayton under identical circumstances.
As the pursuit continues, "Southern Gentleman" Slayton kills three members of his gang for real and/or imagined offenses.
Slayton is out of ammunition, and Warren eventually wins a lengthy fistfight that begins at the top of a steep hill and slowly and dangerously progresses to ground level.
