Eldest begins right after Eragon ends.
Ajihad, leader of the Varden is ambushed by a group of Urgals, which leads to his death. It turns out that the Twins have betrayed the Varden by arranging the ambush and kidnapping Murtagh. Eragon, who witnessed Ajihad's death, is summoned to the Council of Elders to help chose the new leader of the Varden. They want to choose Ajihad's daughter Nasuada as their new leader, as they want to use her as a puppet for their wishes. Eragon agrees with their choice and agrees to pledge his fealty. When the Council tells Nasuada of their decision, Eragon stuns the Council by swearing fealty to Nasuada instead of them, and it turns out that Nasuada isn't as easy to control as they first thought.
Meanwhile, back at Carvahall, Roran has returned to his home after he heard of Garrow's death, which he blames on Eragon for bring the blue stone to their house. While he is trying to tell Sloan that he wants to marry his daughter Katrina, Blador, one of Horst's sons, tells them that he has spotted the Ra'zac and thirty Imperial soldiers camped nearby. Roran then hides in the Spine.
Saphira promises to the dwarf king Hrothgar to repair the Isidar Mithrim after she and Arya destroyed it to save Eragon from Durza. She then gets drunk at a dwarf feast, which she is afterwards informed that she will be the subject of a ballad for many years to come. At Ajiha's funeral, Nasuada is officially announced as the new leader of the Varden, and Eragon publically swears fealty to her. Eragon meets a sorceress named Trianna, who tries to woo him to join the Du Vrangr Gata (ancient language for The Wandering Path), which is a group of magic useres who serve in the Varden. She is chased away by Saphira. Before Eragon and Saphira leave for Ellesméra, Orik comes to him with a gift from Horthagr: a chance to be adopted into the dwarf clan Dûrgrimst Ingeitum. Eragon accepts, becoming the first human to join a dwarf clan. Eragon and Saphira say goodbye to Angela and Solembum, who will be accompanying the Varden. The two leave for Ellesméra, and are accompanied by Arya and Orik.
Roran hears from Albriech, one of Horst's sons, that the brewer Quimby has been eaten by the Ra'zac. Roran and several other men, including Quimby's thirteen-year-old son named Nolfarvrell, decide to fight back. They are able to kill some of the soldiers, but some of their own are also killed in the process. They build a wall against the Ra'zac. Shortly after, there is another battle, where more villagers die, including a ten year old named Elmund. Quimby's widow, Birgit, tells Roran that she has a blood feud against him, because of him being related to Eragon, and also because she feels that Roran is the cause of her husband's death. Roran and Katrina are finally engaged. The Ra'zac then make a threat, saying that if the villagers give up Roran, they will be enslaved, but if they don't, they'll be killed.
Eragon, Saphira, Arya, and Orik stop at a dwarf city called Tarnag. However, it turns out that not all the dwarf clans are happy about Eragon being adopted to Dûrgrimst Ingeitum, especially a clan named Dûrgrimst Az Swelden rak Anhûin. which hates all Dragon Riders. Eragon visits a dwarf temple called Celbedeil, where he learns about their religion and six deities. The group leaves when the city becomes increasingly unstable.

Arya teaches Eragon how to act among the elves.
The grouo arrives at the elven outpost of Ceris. There, two elves named Lifaen and Narí, who accompany them.

He even convinces Katrina o go, despite the fact that her father hates the Spine. Sloan then learns and forces himself to accept that Roran and Katrina are engaged. However, Sloan betrays the villagers by murdering the watchman Byrd, and allowing the Ra'zac to kidnap Katrina and wound Roran. Afterwards, Roran convinces most of the villagers to go to Surda.

In Ellesméra, the group meets the elven Queen Islanzadí. It turns out that Arya is her daughter. Eragon meets a female werecat named Maud and a talking bird called Blagden. Then, Eragon meets a Dragon Rider called Oromis, whom Eragon knows as the Mourning Sage/Togira Ikonoka (ancient language for The Cripple who is Whole), and his three legged dragon named Glaedr. It was they who taught Brom, Morzan, and their dragons. Oromis is weak, and therefore is not able to take part in the war against Galbatorix, but has woven countless spells around himself so that he is able to live long enough to train the next Rider.
Eragon and Saphira begin their training under Oromis and Glaedr. It turns out that the baby whom Eragon blessed in the first book, he actually cursed since the blessing he used, 'atra guliä un ilian tauthr ono un atra ono waíse skölir fra rauthr,’ means 'may luck and happiness follow you and may you be a shield from misfortune,' instead of 'may luck and happiness follow you and may you be shielded from misfortune.' Arya introduces him to a female smith Rhunön who made all of the Rider's swords, including Zar'roc, though she has sworn an oath to never make another weapon ever again. Arya shows a tree to Eragon called the Menoa Tree, which was once an elf woman. Eragon remembers the tree from the advice that Solembum gave to him in the first book.

Trying to finance the Varden, Nasuada tells Trianna to magically create lace. Nasuada meets Elva, the cursed baby, who now appears to be four years old and is able to speak due to the curse that Eragon put on her. Instead of being shielded from misfortune, she shields others from misfortune. After complaints from the lace guild, King Orrin vetoes the lace idea.

He also learns that the elves are atheists, vegetarians, and practice civil unions, instead of marriage.
Roran and the other villagers arrive at the port city of Narda. They find three barges and convince the captain Clovis to take them to Teirm.

Then Iduna and Neya, combined female elves with a dragon tattoo on their body start dancing. As they start dancing faster and faster, the dragon comes to life and gives Eragon a gift. The gift is that it washes his body of all impurities, including the wound on his back, and makes him an elf-human hybrid.

They stop at Aberon to find out that the battle will be on the Burning Plains.

Some Urgals, led by Nar Garzhvog, who have been freed from Durza's spell, ask to join the Varden. At first, Eragon hates the idea, but after he looks into the mind of the Ugals, and with the help of Nasuada and Saphira, he accepts them into the ranks of the Varden. The battle begins, and the two armies fight each other. The tide of the battle shifts between the two sides. Eragon and Saphira fight for the Varden, and the Twins are there fighting for the Empire.

The book ends by saying that the story will be continued in Brisingr.
Although the back of the Eragon DVD cover says that it was the first movie in the Inheritance Film Trilogy (before the book series was split into four parts), as of 2014, there has been no plans of making an Eldest movie. However, if they do, and it is a continuation of the first movie, there would need to be major plot elements crucial to Eldest that would need to be addressed since they were left out in the first film. The best possible option would be to remake the whole Inheritance Film Cycle.
