Mabel and Dipper Gleeful are the most popular, attractive, nicest, and flawless people in the town of Gravity Ascends. As you would think... On the inside, they have a side that no one has ever seen...
Gideon Pines isn't too ecstatic to visit his Uncle Bud and the sleepy town of Gravity Ascends, not because of his uncle himself, just that the town let off a weird vibe. Until one fateful day, he discovers something interesting... His best friend Pacifica Southeast on the other hand, is super excited to explore the town with Gideon and spend the best summer with him! (Which may or may not happen.)
When the perfect twins of Gravity Ascends find out that their arch rival, Bud Gleeful (who also own their business nemesis, the Tent of Telepathy) has his nephew and his best friend coming along, the best friends may be in for an interesting summer vacation.
