It's Scooby-Doo and the gang, but this time Fred is...one of the undead!
While the resurrected Fred Jones unleashes his army of monsters on Scooby and the gang, Daphne continues to spiral further into guilt and depression, terrified of losing Fred twice. Fortunately, the gang has another secret weapon: Scrappy-Doo and his mysterious mentor.
Is this the end for the Scooby gang, and perhaps all of humanity, or will Daphne's love for her resurrected boyfriend win out in the end?
