Having fled the bloodbath at the Rollerdome in My Super Psycho Sweet 16, Skye goes in search of the mother who abandoned her as a baby, a woman she barely remembers. Her journey takes her to the quiet town of Mill Basin, where she finds her mother, Carolyn, now married to a wealthy real estate developer. Taken in by Carolyn and Skye's half-sister, Alex, Skye believes she's finally found a safe haven. As the bond between Skye and Alex grows, Skye is introduced to Alex's manipulative best friend, Zoe, and her dream guy, wanna-be DJ, James (aka Jams). Despite Zoe's suspicions, Skye attempts to keep the truth about her father a secret, even from Alex. But Skye's past is about to catch up with her. Brigg is unable to forget Skye and convinces Derek to help him find her. And they're not the only ones on her trail. Charlie Rotter has followed Skye to Mill Basin, and the corpses are starting to pile up. When Alex throws a party on the same night as Skye's 16th birthday, her weekend rager becomes the terrifying setting for a Rotter family reunion and one killer party!
