West Hollywood, circa late-1979. The LA punk rock scene is burgeoning, as is the career of Sugar Smith, an aspiring punk rock singer. Sugar has just landed a gig with Snake Pit, house band at the famed Viper Den, and the hottest punk group in town. But just as everything seems to be going her way, the murder of Snake Pit’s former singer—the very singer Sugar just replaced in a less-than-friendly coup—threatens to destroy Sugar’s entire life. The murderer is out for revenge: Sugar’s life, career, and family—her brother JJ and her younger half-siblings—are all under the gun. Sugar embarks on a desperate quest to find and stop the killer before he or she can carry out the rest of their nefarious plan to ruin her life and the lives of those closest to her.
