The Hedge Knight (2005) (edit title/settings)

A hedge knight, Ser Arlan of Pennytree, has died during the night. His squire, a large young man named Dunk, buries him and pays his last respects. After considering several options, Dunk decides to continue his journey to Ashford and compete in the tourney as a knight. He adopts Ser Arlan's armor as his own, as well as his equipment, three horses, and remaining monies. At an inn on the road, he meets a boy with a shaved head named Egg, who offers to become his squire. Despite the fact that Dunk, calling himself Ser Duncan the Tall, declines the offer, Egg secretly follows him to Ashford. Impressed by the boy's spirit, Dunk takes him on as his own squire for the upcoming tourney.
At Ashford, Dunk sells one of his horses so he can commission a suit of armor by the smith Pate. He also befriends Ser Steffon Fossoway's squire and cousin, Raymun Fossoway. Without proof of his knighthood, however, he is nearly barred from competition until Prince Baelor Targaryen vouches for him. Baelor tells Dunk that as he is not of Ser Arlan's family, he cannot use his arms, so Dunk commissions a Dornish puppeteer girl to paint a new one. Dunk watches the first day of competition amongst the commoners, with Egg on his shoulders. After several spectacular tilts, the day ends after Prince Aerion Targaryen disgraces himself by killing Ser Humphrey Hardyng's horse.
That night, when Dunk retires into the Fossoways' tent to drink with Raymun, Egg informs that the puppeteer girl he had met earlier is being beaten by Prince Aerion. Dunk leaps to her defense and attacks Aerion, striking him in the face. As the royal guard arrests Dunk, Egg reveals himself to be Aerion's brother, Prince Aegon. Imprisoned, Dunk is visited by Egg, who tells that he was meant to be Prince Daeron's, his older brother's, squire. Being a poor warrior, Daeron stole away from the escort, leading Aegon to pose as Egg in order to fulfill his dream of being a squire. After meeting Prince Baelor again, Dunk chooses to take a trial by combat rather than undergo mutilation (the removal of the offending hand and foot which he used to assault a royal prince). Prince Aerion demands the combat to be a Trial of Seven, as his brother, Prince Daeron, the drunkard from the inn, had also accused Dunk of kidnapping Aegon from his charge. The council of lords, including Lord Ashford, Baelor and Aerion's father, Maekar, have no choice but to accept the demand. Dunk must find six champions to fight with him against seven accusing knights, or he must forfeit.
Steffon Fossoway is the first ally Dunk finds. He promises to bring Dunk more champions, as does Raymun. Egg also promises to bring more champions for Dunk's cause. Prince Daeron, also called the Drunken, appears in the tent. He confesses Egg's earlier accusations, and that he fabricated his own charges at the trial as he was embarrassed of losing track of his brother while in drunken stupor. He warns Dunk that his father will have three knights of the Kingsguard fight in the trial. He also tells Dunk of an ominous dream where he saw Dunk with a dead dragon, the symbol of House Targaryen, and assures that his dreams always come true.
Dunk is met again by Pate, who was trusted by the puppeteer girl with Dunk's new shield. At the morning of the trial, Raymun returns with Ser Humfrey Hardyng and Ser Humpfrey Beesbury, good-brothers seeking revenge for the grievance Aerion committed against Hardyng. Aegon brings Ser Robyn Rhysling and Ser Lyonel Baratheon (called the "Laughing Storm"), both eager for the glory of competing in the first Trial of Seven in a century. Steffon returns only to say he has decided to fight with the accusers for the reward of a lordship. Angered by his cousin's treachery, Raymun begs to be knighted and fight in Steffon's place. Dunk hesitates, as the truth to his own knighthood is questionable, and knighting Raymun would also jeopardize his future as well. Dunk is called away by Lord Ashford, and Lyonel grants Raymun his knighthood. Still needing a seventh champion, Dunk appeals unsuccessfully to the crowd. Finally, Prince Baelor announces that he will champion Dunk himself, though the accusers include three of his family members.
The fourteen champions line their mounts along opposite sides of the tourney grounds and charge. Dunk tilts against Aerion, but is quickly unhorsed. Though nearly defeated, Dunk manages to grapple Aerion and use his size advantage and streetfighting style to pummel Aerion into submission with his own shield. Aerion recants his accusation, ending the Trial. The fighting costs the lives of both Humphreys. After the battle, Baelor approaches Dunk to congratulate him, and begins to act drunkenly. When his crushed helm is removed, it is shown that the weaker armor made for his son did not protect him from a blow which has crushed in his skull, fulfilling Daeron's prophetic dream. Prince Maekar meets with Dunk after the funeral, revealing that it was his mace that killed Baelor. He regrets Aerion's behavior and offers Dunk a position in his household to train Aegon. Dunk insists on being allowed to travel, and offers to take Aegon as his squire to learn to be a better knight than Aerion. Maekar agrees, making sure Aegon continues to use his alias of Egg to avoid scandal. Dunk and Egg set out to Dorne, in search of the puppeteer whom Dunk had saved.
