De tieners Fred, Velma, Daphne en Shaggy worden beschuldigd van een grap en geschorst van Coolsville High. En hoewel ze elkaar niet kennen en hun karakters ver uiteenlopen, besluiten de vier tieners hun naam te zuiveren en samen te werken om het mysterie op te lossen. En hierbij werkt het viertal samen met de pratende detective-hond Scooby Doo.
Nee, helaas is Scooby-Doo! The Mystery Begins nog niet beschikbaar op Netflix in Nederland.
