Set during the Joseon Dynasty (1392–1910), 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.
