Bowen, portrayed by Dennis Quaid, is a steadfast knight who upholds the ancient principles of honor, valor, and chivalry. He mentors his young pupil, Einon, played by Lee Oakes, teaching him not only the art of swordsmanship but also the true values of knighthood. As the son of King Freyne and heir to the throne, Einon becomes embroiled in a brutal peasant rebellion, which his mentor urges him to witness firsthand. Bowen emphasizes the crucial distinction between noble warfare and mindless slaughter.
In the chaos of battle, fate takes a dark turn when Einon is accidentally impaled during a scuffle with a peasant girl named Sandra. Aislinn, Einon's mother, portrayed by Julie Christie, demands that only Bowen remain by her son’s side as she desperately seeks help. As she grieves over her wounded child, she gazes at a dragon statuette and utters, > "Not all." This sparks a series of supernatural events as Aislinn seeks the assistance of a dragon dwelling in a nearby cave.
Initially reluctant, the dragon eventually agrees to help, convinced by Aislinn that her son has the potential to be a great leader, unlike his late father. The dragon extracts half of his heart and gives it to Einon, binding their fates together. As Einon recovers, he is commanded to fulfill his promise to become a noble king, yet he disappointingly turns out to be as tyrannical as his father, brutally quelling the peasant rebellion and inflicting horrific punishments.
Fast forward twelve years, and Bowen has become a dragon-hunting mercenary, hardening his heart toward his former beliefs. He encounters Brother Gilbert, a monk who teams up with him to pen poetry about his exploits. Meanwhile, Einon—now a cruel ruler—kills the once-great leader of the rebellion, Readbeard, leaving his daughter, Kara, portrayed by Dina Meyer, in sorrow.
During his dragon-slaying quests, Bowen reluctantly crosses paths with another dragon, voiced by Sean Connery. Their initial confrontation leads to an unusual alliance as the dragon offers Bowen a unique form of protection, encouraging him to "kill" him in a staged battle to earn the villagers' trust. Aislinn, horror-struck at her son’s behavior, facilitates an escape path for Kara, who longs to ignite another rebellion.
A conflict brews as Einon learns of Bowen and the dragon's partnership. Prodded by desperation, Kara seeks to persuade Bowen to rekindle the fight against Einon, yet he remains torn between vengeance and honor. A thrillingly climactic confrontation at Avalon between Bowen and Einon culminates in a desperate quest for redemption, revealing the intrinsic connection between Einon and the dragon.
As death and betrayal linger over the heroes, Bowen grapples with his principles, ultimately faced with the seemingly insurmountable challenge of defeating Einon without sacrificing his newfound friend, Draco. As their fates interweave through shared pain and loyalty, Bowen finds himself at a crossroads.
In a heartbreaking battle of wills, where devotion and sacrifice clash, Bowen must make a grave choice. Ultimately, with the weight of his past weighing heavily on him, he plunges an axe into Draco's heart, leading to a harrowing climax where Einon meets his demise as well. In the aftermath of victory, Bowen, along with Kara, Brother Gilbert, and the villagers, mourn the loss of Draco, who inspires them to look to the heavens.
As they gather around his fading form, Bowen witnesses Draco ascend into the sky, symbolizing not only the redemption of the dragon but also the restoration of hope and honor within Bowen's heart. In this profound moment, Draco's spirit is welcomed into the constellation above, signifying the end of an era and the beginning of a legacy of courage and unity.
