I Am the King

The movie depicts the three months before Choong-nyung (the future Sejong the Great) becomes king. The Annals of the Joseon Dynasty, which follow the history of the Joseon period between 1413 and 1865, leave out records of this crucial period. While to future generations King Sejong would stand as a legendary figure for his creation of the Korean alphabet and advancing the country's scientific research and law, as Prince Choong-nyung he was known to be a bit of a reclusive bookworm.^[5]

When his older brothers Yangnyeong and Hyoryeong fail to impress their father King Taejong, the king makes a royal command for Choong-nyung to become the next ruler of the kingdom instead. The prince, who strongly refuses to become the king and just wants to live a happy and stress-free life buried in his books, chooses to escape the palace before his coronation ceremony.

After hours of contemplation, Choong-nyung escapes by climbing over the palace wall. There he runs into a bad-tempered drunken slave named Deok-chil, who happens to be at the palace to save the love of his life who was captured by government officials and put in prison for being the daughter of a suspected spy.

Deok-chil perfectly resembles the prince, so Choong-nyung instantly grabs the chance to disguise himself as a slave and they exchange clothes with each other. In a terrible twist of fate, when Choong-nyung wakes up after being knocked unconscious, he is mistaken for a slave and Deok-chil gets put on the throne. As Choong-nyung ventures outside the palace walls, he begins to open his eyes to the people living in extreme poverty and experiences the life of the common man.^[6]
