The film opens at an unspecified date in the early 21st century. During construction on the London Underground, workers penetrate a cave. A huge European dragon emerges from hibernation, incinerating the workers with its breath. The only survivor is a boy, Quinn Abercromby (Ben Thornton), whose mother, Karen (Alice Krige) - the construction crew chief - is crushed to death protecting him. The dragon flies out of the Underground, and soon more dragons appear. It is revealed through newspaper clippings and the narration that dragons are the species responsible for the extinction of the dinosaurs. They are speculated to hibernate after destroying most living creatures until the planet repopulates. Mankind's militaristic resistance, including nuclear weapons in 2010, only hastens the destruction, and by 2020, humans are Endangered species.
An English knight of chivalry, Bowen, mentors a Saxons prince named Einon, in his ideals with the hope that he will be a better king than his tyrannical father King Freyne. While suppressing a peasant rebellion, the king is killed and Kara, a young peasant girl, accidentally causes Einon to be mortally wounded. Einon's Celts mother, Queen Aislinn, has him taken before a dragon and asks it to save the boy's life. The dragon replaces Einon's wounded heart with half of its own on the promise that Einon will rule with justice and virtue. However, Einon proves even more tyrannical than his father by enslaving the former rebels and forcing them to rebuild a Roman Empire castle. Bowen, believing the dragon's heart twisted Einon, swears vengeance on all dragons.
