A young woman named Hong Chun Ki is a painter during the Joseon Dynasty, which is quite uncommon in Joseon Korea, because Confucian norms forbid women from engaging in such activities. Despite being born without seeing, she managed to develop a sense of vision. She has now been admitted into the nation’s premier art college.
She encounters Ha Ram, an astrologer who was born seeing but lost his vision as a child, one day. Ha Ram’s fate is the complete reverse of her own. Nevertheless, despite being blind, he also possesses a remarkable gift that enables him to foretell the future by tracking the movement of the sky at night.
The two become embroiled in the goings-on at the royal court, particularly those involving two princes: the feisty Prince Yang Myung and the ruthless, cunning Prince Joo Hyang, who is vying to succeed Joseon the Great.
