The Arizona Raiders

Laramie Nelson (Buster Crabbe) falsely accused of horse-stealing, is
about to be strung up by a posse when a sudden lurch of his horse
knocks down his would-be executioners, and he makes his escape. He
soon comes upon another hanging posse and saves "Honest" Tracks
Williams (Raymond Hatton), accused of a long, long list of minor
crimes, and the two ride off together. They come to a small Arizona
town, and their first encounter is with attorney Monroe Adams (Grant
Withers) and his client, Harriet Lindsay (Marsha Hunt), owner of the
large, prosperous Spanish Peaks ranch. Harriet and Adams have come to
town to stop the marriage of her young sister, Lenta (Betty Jane
Rhodes), to shy young Alonzo "Lonesome" Mulhall (Johnny Downs). They
are successful, and Alonzo is jailed, along with Tracks, following his
attempt to shoot up the town. Tracks offers to arrange an elopement
for Alonzo as soon as they are out of jail. Laramie gets them out of
jail ahead of schedule by stampeding a herd of cattle through town
during a Fourth of July celebration. The three head for Harriet's
ranch, where Laramie and Tracks get jobs as ranch hands, while Alonzo
hides out in the brush. Laramie soon discovers that Adams is in league
with ranch foreman Luke Arledge (Don Rowan) to steal Harriet's herd of
fine horses.
