In the early 1970s, 25 free spirits found each other in San Francisco's Haight-Ashbury neighborhood and formed the Kerista Commune. For two decades, they lived as one family, loving freely, raising children together, and making millions selling Apple computers. But if the alternative society they built was fantastically alluring, it was also fragile, and a quarter century after they voted to dissolve their commune, the former members are still debating what their experiment can teach us about human nature, and whether their utopia was actually a cult in disguise.
