When the members of Mystery Inc. decide to take a vacation and leave behind the stressful world of solving mysteries, they head to a remote Caribbean island in search of relaxation and fun. But what they find is the surprise of their lives. The island, inhabited by a charming community of locals, is famous for its legends about an ancient zombie cult. Soon, the group realizes that the stories are not just tales from the local culture. The tranquility of their vacation turns into a race against time when zombies begin to appear on the island.
As they try to enjoy their time, Scooby-Doo and the gang find themselves caught up in a series of supernatural events that challenge their idea of what a "mystery" is. Velma, Daphne, Fred, Shaggy, and the easily frightened Scooby realize that they must uncover the truth behind the zombies, who seem to have a very real and dangerous agenda. With a touch of nostalgia for the gang's classic investigations, this adventure features unexpected twists, an air of mystery, and a villain that straddles the line between the mythical and the terrifying.
Along the way, the friends confront their own fears and limitations, rediscovering the importance of friendship and teamwork. A fun experience that blends horror with the trademark humor of Scooby-Doo, this adventure is both a tribute to the classics of the genre and a fresh, exciting experience for new generations.
