My Super Psycho Sweet 16 (film series)

Madison Penrose, spoiled throughout her life, convinces her rich parents to re-open a nearby rollerdome for her Sweet 16 birthday party. The rollerdome once closed because a series of brutal murders took place at the locale, and, of course, the killer returns to wreak havoc during her party.

Birthday Theme: Madison Penrose (Julianna Guill).

Skye Rotter is on the run, having fled the Roller Dome massacre from the end of the first movie. With nowhere left to turn, Skye heads to the quiet town of Mill Basin and the mother who abandoned her years ago. There, she meets her younger half-sister Alex and Alex's manipulative best friend Zoe. Skye hopes she's finally found safety in her new family, but she's about to learn she can't outrun her past. While her friends Brigg and Derek desperately try to locate her, Charlie Rotter comes to town with one bloody mission: to turn Skye's upcoming birthday into a Sweet 16 she'll never forget, turning a weekend rager into the savage setting for a Rotter family reunion.

But before Skye can truly escape her dark past, there's still one last party she has to attend - her estranged sister Alex is having her Sweet 16, and someone has made certain the Lord of the Rink's bloody legacy lives on. One way or another, the party will end here.
