Set during the Joseon Dynasty (1392ΓÇô1910), Choi Cheon Joong is the kingdom's most respected fortuneteller and face reader — also known for his skills in gambling and martial arts. Loved by the people and driven by a strong sense of patriotism, he takes on his greatest mission yet: to overthrow the corrupt ruling regime and help a virtuous young prince from a minor royal line rise to the throne.

Cheon Joong believes this prince is the rightful leader and also identifies a humble street girl as the perfect future queen. To make this vision a reality, he uses all his talents and is joined by Princess Hwang Bong Ryun, a gifted fortune-teller herself. As they work together to change the course of history, a deep bond begins to grow between them.
