Following the events of the previous Fall Formal, Sunset had wanted to reach out to everyone at CHS, much like how Twilight reached out to her. But the unforgiving nature of the students, as well as the scars she received that night only reminded her of how much she had lost since coming here. But when Twilight returns to stop a group of creatures called the Sirens, will she be able to earn that redemption? And while Sunset and the Humane 6 fight the Sirens, the mysterious man responsible for Sunset's scars watches on.
