Scooby-Doo! and the Legend of the Vampire

The Mystery Inc. gang travels to a music contest held at Vampire Rock near Sydney and learns the site is tied to a local myth about the Yowie Yahoo. They reunite with their friends, including the Hex Girls, and meet the festival organizers and rivals. The atmosphere is festive but carries a hint of danger as rumors of vampires begin to surface.

The team reconnects with the Hex Girls and meets festival managers Daniel and Russell, as well as Malcolm, who disapproves of the event. They learn that a band called Wildwind were turned into vampires by the Yowie Yahoo and that the creature haunts Vampire Rock. The discovery links the festival to a deeper, supernatural threat.

Fred enters Mystery Inc. into the contest as a ploy to lure out the Yowie Yahoo. The others watch suspicious activity around the competition while the plan unfolds. The stakes rise as costumes and performances take on a darker edge.

Fred, Daphne, and Velma search Ridgeway's trailer and uncover mementos from Wildwind, suggesting a hidden agenda. Ridgeway is nowhere to be found, heightening suspicions about his role. The team suspects he is pressuring others and possibly trying to manipulate the Hex Girls.

It is revealed that Ridgeway once managed Wildwind and now aims to sign the Hex Girls as his new clients. His pushy behavior and scheming actions point to a broader plan behind the festival drama. The group resolves to keep a closer eye on him.

While the Mystery Inc. members split up, Wildwind launches an attack and kidnaps the Bad Omens and the Hex Girls. The festival descends into chaos as the threat of real vampires becomes apparent. The remaining contestants scramble to stay safe.

Shaggy and Scooby stay outside to guard food stands, while Fred, Daphne, and Velma pursue Wildwind into nearby caves. Inside, they confront vampire forces and are forced to retreat after a tense encounter. Their courage is tested as the mystery deepens.

The trio discovers film equipment and a suspicious setup while being chased by vampires. They finally escape the danger by fleeing back out of the caves, narrowly avoiding capture. The discovery hints at a larger scheme behind the vampiric disguise.

The group is cornered by the vampires, but Scooby's collar reflects the approaching sunrise, dispelling the immediate threat. Despite the daylight, Wildwind remains determined and chases them further, revealing their resilience. Daniel helps steer the plan to trap them.

The gang corners and unmasks Wildwind, exposing Russell and the Two Skinny Dudes as the culprits in disguise. They had masqueraded as vampires to sabotage the contest and revive their careers under a new look. The truth exposes a human conspiracy behind the supposed supernatural threat.

Russell and the Two Skinny Dudes explain their plan: restart their careers by fooling everyone with costumes and a hologram of the Yowie Yahoo. They also orchestrated the diversions that sent rivals on Great Barrier Reef tours and abandoned the Hex Girls when they refused to cooperate. The betrayal is brutal and reveals their true motives.

Mystery Inc. rescues the Hex Girls, and Malcolm returns them to safety. With the villains in custody, Daniel declares Mystery Inc. the winners by default. The team earns respect for their bravery and quick thinking under pressure.

Wildwind is arrested and taken into custody, ending the immediate vampiric threat. The community regains its composure as the truth about the plot comes out. The Hex Girls and Mystery Inc. prepare for a celebratory moment that seals their new friendship.

Daniel announces Mystery Inc. as the contest winners by default, and the gang teams up with the Hex Girls for a final performance. The crowd cheers as they close the night with music and victory, sealing their status as heroes of the festival.
