Scooby Doo and the Mystery Inc. gang take their animated antics to the big screen as a live-action movie. In this story, Fred, Daphne, Velma and Shaggy have a bit of a falling out and go their separate ways, but they're drawn back together again by fate, in this case taking the form of the mysterious Spooky Island amusement park and the strange behavior being exhibited by the young visitors to the attraction. This is a case that only the Mystery Machine gang can tackle - if only they can get over their differences.
