Fred Jones, Daphne Blake, Velma Dinkley, Shaggy Rogers and Scooby-Doo are a team of teenage mystery solvers who live in the small town of Crystal Cove, the self-proclaimed "Most Hauntedest Place on Earth". The allegedly "cursed" town's long history of strange disappearances and ghost and monster sightings form the basis for its thriving tourist industry; as such, the adults of the town (chief among them being Fred's father Mayor Fred Jones Sr. and Sheriff Bronson Stone) are not happy that the kids are debunking all the supernatural goings-on that bring in so much revenue as the overwrought schemes of charlatans and criminals.
In addition to the traditional cases they always solve, the team finds itself being nudged into the uncovering of a dark secret that is hidden in the past of Crystal Cove. Following cryptic hints from a faceless mystery-man known only as "Mr. E." (a play on "mystery"), the gang unearths the legend of a cursed Conquistador treasure, the secret history of Crystal Cove's founding Darrow Family, and the mysterious, unsolved disappearance of four mystery-solving youths and their pet bird—the original Mystery Incorporated. Standing in the way of solving this mystery, however, there are the romantic entanglements pulling the kids apart: Shaggy finds himself unable to put his new romance with Velma ahead of his longtime friendship with Scooby, while Daphne pines for a trap-obsessed Fred, who obliviously struggles to realize he shares her feelings, too.
The return of the original Mystery Incorporated to Crystal Cove begins a race between the two groups to locate the pieces of the enigmatic planispheric disk, which will point the way to the cursed treasure beneath the town. As the pieces are gathered, it becomes apparent that these two groups are not the only teams of mystery-solvers that have lived in Crystal Cove: many similar groups, always made up of four humans and an animal, have existed, and the secret behind their centuries-long connection will reveal the truth behind the curse of Crystal Cove. The fate of both the gang's friendship and all of reality itself hangs in the balance as extradimensional forces gather in preparation, and the time of Nibiru draws near.
