The story is set in the Mystery Shack during the summer. Stan Pines has been living under his brother Ford's identity, but now Ford has returned and wants his life back. The narrative begins as Guest overhears a tense argument between the brothers. They are striking a deal: Stan can stay for the summer to watch the kids, Mabel and Dipper, but must leave and return Ford's identity and house afterward. Stan's one condition is that Ford stays away from the children, fearing for their safety.
Stan Pines is a fiercely protective great-uncle to Mabel and Dipper, whom he considers his only family. He has been running the 'Mystery Shack' tourist trap. His twin brother, Ford Pines, is a mysterious figure whose life seems to involve danger, prompting Stan to keep him away from the children. Mabel and Dipper are twins spending the summer at the Shack, caught in the middle of their great-uncles' drama.
Mabel and Dipper were in their room while Stan and Ford argued
Okay Stan here's the deal, you can stay here for the summer to watch the kids, but when the summer's over, you give me my house back, you give me my name back, and this mystery shack junk is over for good
Fine, on one condition, you stay away from the kids, I don't want them in danger, because as far as I'm concerned, they're the only family I have left
