Oswaldo's birthday arrived, uhul!! Only it's Monday, race day and he's super down about it. Well, Leia prepared a surprise for him: she planned a Gamebook around the neighborhood especially for Oswaldo. So, together with Tobias, they walk around town dressed as medieval heroes, and Oswaldo has to follow the script Leia wrote for him, solving questions that will lead him to the lost treasure (it's a surprise party, don't count for him!) But things begin to go wrong when Leia finds out that Tobias decides to rewrite the end of the game without telling her. And as Tobias is a bit of an airhead, they find themselves totally unscripted and in the middle of a perilous journey through the unfamiliar streets of the city. Worst of all, Oswaldo still believes that everything is part of the game.
