Plot synopsis: The feud between the Hatfields and McCoys is perhaps the most famous family conflict in American history. As legend has it, two neighboring families in the backwoods of Appalachia waged a crude and bloody war against each other over a stolen hog, an illicit romance, and longstanding grudges. Yet the events that took place near the end of the 19th century between the Hatfields and McCoys are part of a much richer and more complex narrative of the American experience.
