Wherein a dragon saves a terrible person's life and everyone blames the dragon for said terrible person's terribleness. Its a funny old world we lived in back in 984 AD.
So yeah, the plot here is that a oppressive king dies in a moronic manner and his awful Joffreyesque turd of a child becomes king. Before he can reimplement prima nocta, a girl falls onto him; knocking him into a lethal cheese cart. Yes that's right. Before the movie even starts up, the villain has been killed by a cheese cart. So his mentor, Bowen (played by Dennis Quaid) takes him up to a dragon's cave where Draco (Sean Connery) takes a chunk of his heart and stuffs into said brat and revives him, all while making him swear an oath to be a just and kind king. Before the little wanker can make it back to his castle, he's already issued a decree to enslave the people to build a vanity project for him. Bowen, being the perfect judge of character that he is, blames Draco for King Twat's cruelty and vows to hunt him to the ends of the earth.
