The Travels of Jaimie McPheeters S01E13 - The Day of the Misfits

A father kidnaps Doc to tend his pregnant daughter (Mariette Hartley) and perhaps marry her. A group of miners come to Doc with gold nuggets and offer to show him the location of the mine if he will attend to the pregnant daughter of the camp's leader. When he hesitates, their guns give him no choice in the matter. Jaimie secretly follows him to the camp, where Doc learns that the young woman is four months from giving birth, and that the miners want him to stay with her for at least that long
