As Summer had passed its midpoint, Sunset and Sci-Twi are visiting Princess Twilight et al, all for them to attend the once a jubilee Whirling Constellation Music Festival. For Sunset and Pinkie, this might be the only time they could catch their favorite duet, PostCrush, before the duo calls their productive but short career over.

However, after Pinkie's want for thrills caused the two to miss the likely last show of PostCrush, Sunset bemoans and asks for a repeat of that day. When dawn arrives Sunset soon realizes she stuck repeating the same day.

What caused this loop?
How can she break the loop?
Can she see the duo?
Will her friendship with Pinkie last?

Where do we go? Every day's the same
Did we lose the magic, magic, magic?

Wait... the Dazzlings are back?!
