The once peaceful and prosperous country of Alagaesia is now trapped under the tyranny of the evil king (John Malkovich), hoping that the gods will save the people who dare not speak out. One day, Eragon (Ed Speleers), a young farmer, found a strange stone in the forest, but it turned out to be a dragon egg, hatching a blue flying dragon. Eragon named the little dragon "Saphira". After meeting the prophet Bloom (Jeremy Irons), he realized what kind of opportunity this was - the dragon rider who once guarded this land should come back and lead the people to regain freedom. Under Bloom's guidance, Eragon began to learn swordsmanship and dragon riding skills, and slowly grew from an ordinary boy to a dragon rider with heavy responsibilities. The road ahead is full of dangers, and the road ahead leads to light... This film is adapted from the novel of the same name and is the first in the "Inheritance Trilogy".
