Plot
A prologue set before The 13 Ghosts of Scooby-Doo depicts a young Vincent Van Ghoul and his partner Mortifer hunting down and successfully sealing the final ghost into the Chest of Demons. Mortifer, however, is attacked and seemingly killed by minion ghosts as a tearful Vincent makes his escape. In the opening credits, Vincent recaps the events of the series in which Scooby eventually set the ghosts free once more but would catch all but one with the help of his friends Daphne and Shaggy.
In the present day at Old Timey Toys, Mystery Inc. is forced to retire from solving mysteries after catching a teenager-fearing Farmer Morgan and largely due to the ungrateful Sheriff telling them they could be arrested for "criminal negligence". In addition, Old Timey Toys' owner Mrs. Malvo was handcuffed outside for trying to stop a deal with Farmer Morgan.
The following day, they hold a garage sale and sell items from their old mysteries, even the Mystery Machine, leaving Fred depressed. They then discover the crystal ball that Daphne, Shaggy, and Scooby used to contact Van Ghoul during their ghost recapturing adventures. At that moment, their old friend Van Ghoul contacts the gang about the final ghost. Daphne fills Fred and a skeptical Velma in, and unveils the red van dubbed the Misstery Machine, and the gang start on their journey to meet Van Ghoul.
