The Road to Denver (1955)

"Face-To-Face and Pistol-To-Pistol! BROTHER AGAINST BROTHER!"

The Mayhew brothers flee from one Texas town to another as older brother Bill repeatedly attempts to keep younger brother Sam out of jail. Bill finally gives up on his younger brother and heads for Colorado. He gets a job and all is well until his brother shows up and takes a job that puts them on opposite sides of the law.
