The film takes place in Australia, where the "Vampire Rock Music Festival" is being set up near Vampire Rock, a rock formation shaped like a vampire head. There is a legend of a vampire named the Yowie Yahoo, who lives in the rock. Many people are excited for the event, but some don't think it should take place because it would anger the Yowie Yahoo. One such person is Malcolm Illiwara, even though his grandson Daniel is the manager of the contest. One night, as Malcolm and Daniel watch a sure-to-win performer named Matt Marvelous, the Yowie Yahoo appears. The Yowie Yahoo and its three vampire minions capture Matt Marvelous and take him away. Everyone is scared, and Malcolm blames the contest for what happened.
