Written by Frank Chase, "The Gentle Ones" is the tale of two brothers, both in the horse trading business. Kindhearted Mark (Robert Walker Jr.) is a cowboy who loves horses; his brutal sibling Frank (Pat Conway) is a rancher who likes nothing more than to "break" his horses in the most sadistic manner imaginable. Because Mark has never stood up to his brother, he is regarded as a coward by his girl friend Dana (Lana Wood), but with the help of the Cartwrights Mark proves himself to be the worthier of the two siblings. "The Gentle Ones" originally aired on October 29, 1967. ~ Hal Erickson, Rovi
