When a machine that allows therapists to enter their patients' dreams is stolen, all Hell breaks loose. Only a young female therapist, Paprika, can stop it. Three scientists at the Foundation for Psychiatric Research fail to secure a device they've invented, the D.C. Mini, which allows people to record and watch their dreams. A thief uses the device to enter people's minds, when awake, and distract them with their own dreams and those of others. Chaos ensues. The trio - Chiba, Tokita, and Shima - assisted by a police inspector and by a sprite named Paprika must try to identify the thief as they ward off the thief's attacks on their own psyches. Dreams, reality, and the movies merge, while characters question the limits of science and the wisdom of Big Brother.

The gang goes on a trip to check on Velma's younger sister, Madelyn. She's been studying stage magic at the Whirlen Merlin Magic Academy, where apparently there have been sightings of a giant griffin. The gang decides to investigate. Everybody's favorite canine detective is back again. The Scooby Gang still seem fresh and vibrant in their latest straight-to-DVD adventure, Scooby-Doo: Abracadabra-Doo, over 40 years after their first television appearance. The Mystery Machine is a newer model and now has a very annoying GPS, but that's about all that's changed.
