剧情概要：
What brings my best friends together? For Daphne, Velma, Fred, Shaggy and Shaggy's brave dog Scooby Doo, this is a mystery! Long live version Scooby! The original film 'Mysterious Beginning' takes you back to the first time four teenage detectives (plus a dog detective) met. The children were unfairly accused of performing a terrifying prank full of ghosts, and therefore were suspended from Coolsville High School. In order to clear their charges, they teamed up to solve this supernatural mystery... and then went straight into uninterrupted laughter and adventure. Special fun, special friends, and extra special effects make this "how everything started" story - from the boy meeting a dog to the first trip of a mysterious machine, and so on - a wonderful time for a dog!
