Dipper and Mabel Pines were living a normal life. That is, until they moved to Gravity Falls to spend their sumner. Things got pretty hectic over there, and together they battled monsters that you might believe don't exist. One day, while exploring the woods, they find a strange and beautiful stream. They soon find out that it's supposed to have magical powers, and drink from it. But someone doesn't want them to drink from it, and will take revenge on the Pines family. But who doesn't want the Pines family and their friends drinking out of their river? They'll soon find out...
