Under the rule of King Sejong the Great (Han Suk Kyu), the Joseon Dynasty flourished as scientific advancements and technological developments served to better the lives of the people. Honoring those who made scientific progress, the King sought out the greatest minds in Joseon, celebrating the advancements they made in agriculture, astrology, medicine, and more. With an insatiable thirst for knowledge and a mind inclined to think outside the box, it was only a matter of time before he crossed paths with the brilliant Jang Yeong Sik (Choi Min Sik).
Born a slave, Jang Yeong Sik had no claims to greatness, but his astounding mind and impressive talents eventually earned him a position within the local government. Finding a kindred spirit in Yeong Sik, King Sejong gives the low-born man a position as his science advisor, and together they make great strides in the scientific world. As time passes, their love of scientific research and invention leads them to form an unusual and completely unprecedented friendship.
But the technological advances they make for Joseon catch the eye of the Ming Empire. Wary of Joseon becoming too great, the Chinese Emperor orders an immediate cessation of astrological study and demands that Jang Yeong Sik be handed over at once. Forced to make a terrible choice, King Sejong must decide between the friend he cherishes or the people he was born to protect.
