When Shaggy takes Scooby and Scrappy-Doo to the Southern plantation he's inherited from his Uncle Beauregard, they find a creepy manservant, a collection of ghostly tenants, and a fortune in family jewels hidden somewhere on the estate! Terrified, Scooby and Shaggy call in the services of the Boo Brothers--Freako, Streako and Meako--a team of barely scary ghosts. But as ghosts chase ghosts, they all chase Scooby, Scrappy and Shaggy from one end of the estate to the other, through trap doors and secret tunnels, onto runaway contraptions and into dangerous booby traps, with hairbreadth escapes at every turn!
