The Pines twins were having an ordinary day (by ordinary they mean the usual monster scavenging the rough their trashcan kind of ordinary) in the town of Gravity Falls when a mysterious magician arrives and sets up a, you guessed it, magic show, which somehow attracts every single town folk there is (literally). Is this suspicious magician just doing his job for fun and laughs, or is he playing dumb and is not what he seems?
