Bernie Sanders loses the 2016 Democratic primary to Hillary Clinton, but the film treats that defeat as the start of something rather than the end. Director Kasper Verkaik follows the people who built the campaign's infrastructure and are now figuring out what comes next: Jane O'Meara Sanders, his wife and closest advisor, creative director Arun Chaudhary, and Saikat Chakrabarti, who ran the digital organizing operation that helped the campaign raise a record number of donations from individual citizens rather than corporations or Super PACs. Coders for Sanders volunteers, including Josh Smith, Rapi Castillo, and Jon Culver, talk about the apps and software they built to make grassroots organizing cheap and scalable. Zephyr Teachout, then running for a House seat, appears as one example of the candidates the movement produced. The film's real question is practical rather than nostalgic: can small-dollar fundraising and volunteer tech infrastructure outlast a single losing campaign and actually shift how American elections get financed and run.
