Bernie Sanders' 2016 presidential run gets a reckoning here, made in the shadow of Donald Trump's election. The film traces how a self-described democratic socialist from Vermont built a movement that outlasted his primary defeat, using campaign footage, rally crowds, and interviews to track the argument that Sanders reshaped the Democratic Party even while losing the nomination to Hillary Clinton. It follows the mechanics of an insurgent campaign, the small-dollar donations, the youth turnout, the debates over superdelegates, and asks what happens to a movement's energy when its candidate does not win. The film treats Trump's victory as the event that forces a second look at what Sanders offered and what the party rejected. Supporters, organizers, and commentators weigh in on whether the Sanders coalition was a preview of future politics or a missed opportunity. It closes without a tidy verdict, leaving the impact of the campaign as an open question still being argued out in the party.
