After graduating from Middle School, Aaron and Smolder were getting ready to have some summer fun. But when Aaron's Aunt Marissa and her fiancé, Liam Daniels, go over to Salt Lake City to meet Liam's family, Marissa knew she couldn't leave Aaron and Smolder alone. But luckily, their friends from Equestria had invited them to spend some time with them. Marissa then bought camping supplies for the group to stay in if they decide to visit other places. But that took a huge detour.

Instead of ending up in the Treehouse of Harmony, they somehow ended up at a broken castle with a magic tree grown in the center, as if the tree had destroyed the castle by growing. The seven friends were very confused about that, so they decided to go find some help. Only to figure out where they ended up, or more likely, when. They ended up in Equestria in the next Generation.

Will the Seven friends find their way back to the past? Can the new Mane 6 help them out? Or will they be trapped in the future forever?
