When the Mystery Inc. gang embarks on a new adventure, they find themselves in a haunted mansion that belongs to an old adventurer. Following the owner's death, Scooby-Doo and his friends are summoned to claim an unexpected inheritance: the house. However, the journey turns into a real challenge when they discover that the mansion is inhabited by three comical ghosts known as the Boo Brothers, who have no intention of letting anyone stay.
As Scooby, Shaggy, Fred, Daphne, and Velma try to unravel the mystery, they get caught up in hilarious and terrifying situations, facing clever traps, eerie noises, and comically clumsy specters. With the help of the Boo Brothers, who, despite being ghosts, reveal a fun and charming side, the gang attempts to uncover the connection between the former owner and the mysterious events surrounding the estate's inheritance.
In the end, they not only have to solve the riddle of the house but also learn that not everything is as it seems, even in the supernatural world. With laughs, scares, and of course, plenty of snacks, this adventure promises to keep the audience on the edge of their seats as Scooby and his team discover the true meaning of friendship and bravery, even in the face of the most terrifying specters.
