Filmed in Spain during a hiatus on "Star Trek," this campy Western melodrama stars William Shatner as twin brothers─the sons of a white Yankee and a Native American woman. As the siblings struggle with their cultural identity, they find themselves on opposite sides of the law─resulting in a stunning Shatner-packed smackdown. With Joseph Cotten, Rosanna Yanni, Perla Cristal. AKA: "Hour of Vengeance," "Rio Hondo." 94 min. Widescreen; Soundtrack: English Dolby Digital mono.
