Raw, nostalgic, and lovingly-crafted, Sara Lamm and Mary Wigmore’s feature-length documentary, &quot;A Birth Story: Ina May Gaskin and The Farm Midwives&quot; captures the 1970s countercultural zeitgeist of its titular band of self-taught midwives. Grainy footage depicts the early settlers of The Farm, an intentional community in Tennessee, enacting a utopian mission to “be in community, to raise children in another way, and to take care of the planet.”
