Avid video game designer Artha Penn has no interest in racing real dragons until a legendary black-and-gold dragon named Beau chooses him to be the Dragon Booster.
Desperate to gain control of the city's powerful dragon crews, Word and Moordryd hatch a scheme to bring down the influential leader of the Down City Council.
Parmon duplicates the Dragon Booster suit to help his triple-booked friend, but there's pandemonium when three Dragon Boosters show up to rescue Kitt from Moordryd's clutches.
In his plot to capture Beau, Word drives Artha and his dragon underground to the cave of the Muhorta, an ancient dragon that feeds off Draconium like a vampire.
During a marathon race, Artha and his friends fall into a trap by Moordryd and land in the ancient Track of Doom, realm of the ancient warlike Dragon Prophets. There they must convince Propheci that they have the strength to prevent a new war between dragons and humans.
