After the events of Equestria Girls, Sunset Shimmer has had to adapt to her new normal life at Canterlot High. Slowly but surely, she has found her place within the school and her own circle of friends, becoming a very adept student in her own right.

But a new threat threatens to tarnish all of that for her. A power that seems to hold sway over the entire school itself, even Principal Celestia herself.

His name?

Superintendent Tirek. And he seems determined to make Sunset pay for her past mistakes.
