When Fred, Shaggy, and Scooby get jobs on a construction crew, they discover that the building site is being haunted by the ghost of a man whose house stood on the very spot as the new building.

Willie the Weasel has created a formula that turns him into Mr. Hyde. While the Blue Falcon and Dynomutt are on the trail of the mysterious Mr. Hyde, they encounter the Mystery Inc. gang and Scooby-Doo (who are unaware that Mr. Hyde is a supervillain and not one of their typical "spooks"). In The New Scooby-Doo Movies-fashion, they team up with the Blue Falcon and Dynomutt (who happens to be Scooby's hero) to stop Mr. Hyde who has threaten to turn the entire city into Mr. Hydes unless he is proclaimed Mayor. Fred and the others find a clue (which turns out to be Willie the Weasel's glove) and the Blue Falcon deduces that he is Mr. Hyde. The Blue Falcon and Dynomutt have Mr. Hyde proclaimed Mayor and pretend to be turned in so that Mr. Hyde will lead them to his secret lair, where they can trick him into showing them the antidote to the Hyde formula. Willie the Weasel and his canine partner-in-crime "Snitch" manage to escape. The Blue Falcon and Dynomutt head to the Mayor's mansion to stop Hyde from retrieving his stolen loot. The Mystery Inc. gang setup one of their infamous "Scooby Traps", while the Blue Falcon and Dynomutt confront Mr. Hyde and Snitch. Dynomutt captures Snitch, while the Blue Falcon and the Mystery Inc. crew capture Willie the Weasel/Mr. Hyde.
