Warning: spoilers for Equestria Girls: Rainbow Rocks in the description and story.
After the events of Rainbow Rocks, Sunset grows concerned about what might happen as Senior Prom approaches; Canterlot High doesn't have the best track record when it comes to big events, and she's afraid that, like the last two, this one will also be accompanied by atrocity. Her friends claim that she should relax as there's nothing to worry about, but Sunset retains a nagging fear in her gut that catastrophe is about to strike - again.
However, after she encounters an interesting individual - one that she didn't even know she'd see again - working at Canterlot High, she finds herself with an even bigger problem: figuring out how to, by some miracle, have a date at Senior Prom not go horribly wrong.
