Coming of age in Detroit, Opal believes she can be a star. So when the aspiring British singer/songwriter Neville Charles discovers her at a bar’s amateur night, she takes him up on his offer to make rock music together for the fledgling Rivington Records. In early ’70s New York City, just as she’s finding her niche as part of a flamboyant and funky creative scene, a rival band signed to her label brandishes a Confederate flag at a promotional concert. Decades later, as Opal considers a 2016 reunion with Nev, music journalist S. Sunny Shelton seizes the chance to curate an oral history about her idols. But as her interviews dig deeper, a nasty new allegation from an unexpected source threatens to blow up everything.
