Time Out says
Civil War renegade Cooper fakes death in a shoot-out with Wyatt Earp and heads for Texas to revenge himself on the brothers who massacred his family. A routine plot, but plenty of diversions on the trail - Coop pretending to be a dandified US marshall in frock coat and top hat, horseback chases, furtive romance. The star sleepwalks, though since he's supposed to be the laconic outsider-type, this doesn't matter at all. Impressive production values and blazing Technicolor camerawork by Ernest Haller. Basically a B-Western though.
