17th century Joseon. Princess Jungmyung protected the people and the royal family in a tumultuous period
Princess Jungmyung was the only princess borne by Kim Seonjo, the 14th ruler of the Joseon Dynasty.
But upon the death of King Seonjo, his half-brother, Prince Gwanghae became the next king and led to the death of Jungmyung's brother, Prince Yeongchang while her mother, Queen Inmok was banished. She was suddenly relegated to the commoner's class that brought immeasurable suffering…
When Inmok learned that Princess Jungmyung had a bounty on her head, she had her daughter sent into hiding. A nanny and bodyguard heroically saved Jungmyung from death by assassins, but she found herself having to fend for herself. She lost consciousness and got stranded on a boat sailing to nowhere. She was sold as slave in Dejima (present-day Japan).
After becoming an adult, Jungmyung learned how to handle brimstone better than most men and also a peddler in information in Dejima, a trade city. With help from Hong Joo-won, who was part of a Joseon delegation to Japan, she was able to return to Joseon.
Upon returning to the kingdom, Jungmyung kept her identity as a secret and found her way into the Hwagidogam bureau, a vital royal ministry. She plotted her revenge against Gwanghae, who took away her loved ones. During this time, she also broke the hearts of Hong Joo-won, who serves Gwanghae, and Kang In-woo, who is loyal to King Injo...
