Farmsteaders (10 p.m., PBS / UNC-TV) - This POV documentary follows a family trying to make sustainable farming work in rural Ohio. North Carolina-based director Shaena Mallett, who has worked as a documentary photographer and professor at UNC-Chapel Hill, follows Nick Nolan and his family of eight through the ups and downs of dairy farming in the shadows of corporate agriculture. Each member of the family pitches in, navigating between the two extremes of hardship: from having too little business, to having more business than they can handle.
