Tremors of the earth itself plague the land of Equestria. Soothsayer Twilight hopes to stop them with some help. Together with five strangers, she must travel to a place where nopony has gone before. They must go to where it all began and stop it. Though sometimes, it's more about the journey than the destination.

Ladybug and Cat Noir have to fight a new villain named Solar Flare. During a fight with Solar Flare, Ladybug ends up getting hurt while she only has a limited time left to use her powers before she switches back to Marinette. Can Cat Noir figure out a way to help her before she switches back or will time tell him the secret he wasn't meant to find out? (Rated T just in case.)
