In the Fort Laramie episode titled Still Waters, the atmosphere at the fort shifts dramatically with the arrival of Mrs. Feemster and her Committee on Moral Improvement. Their mission is clear: to impose stricter moral standards on the soldiers, which includes the controversial decision to eliminate beer from the post. This change threatens to disrupt the camaraderie and morale among the troops, who rely on their small comforts to cope with the harsh realities of frontier life.
