The High Chaparral (1967) : 3x18

A former gunfighter's new life as a Cannon ranchhand is jeopardized by four enemies. Other Cannon ranchhands and Johnny's teen-age son, Dan, who are unaware of Johnny's reputation, misinterpret his refusal to wear a gun and otherwise go out of his way to avoid confrontation with anyone. Any doubts as to Rondo's courage are soon dispelled however, when he is challenged by three men out of his past.
