Rio Grande.

As Bruce Lanning posts a "no trespassing" sign at a watering hole on his Circle A ranch, his sister Jane rides up with news that Wes Caven, the hired gun of the Elwood brothers, is looking for him. Soon after, Wes appears and kicks over the sign. Later, Sunset Carson, Wes's boyhood friend, rides into town to invite Wes to become a partner in his new ranch. Just as Wes declines the offer and offers Sunset a job working for the Elwoods instead, Bruce bursts into the saloon, demanding to see Frank Elwood. Not to be confused with the 1950 John Wayne film of the same name
