In 1970, 1,500 hippies and their spiritual guru Stephen Gaskin founded a commune in rural Tennessee, United States. Members gave over their life savings, grew their own food, delivered their babies at home and built a self-sufficient society. Raised in this alternative community by a Jewish mother from Beverly Hills and a Puerto Rican father from the Bronx, filmmakers and sisters Rena and Nadine return for the first time since leaving in 1985. As well as facing their past after years of hiding their upbringing, they chart the rise and fall of America's largest utopian socialist experiment and their own family tree. The nascent idealism of a community destroyed, in part by its own idealism, is reflected in the personal story of a family split apart by differences. American Commune finds inspiration in failure, humour, and most surprisingly, that community values are alive and well in the next generation.
