The abandoned Princess Deok Man (Lee Yo Won) was raised by a maid and grew up to be a wise girl amidst books and knowledges of foreign lands - she's able to read and speak in different languages. At 15 years of age, she went to search for her true identity after being pursued by a man who wanted to capture her. She then became a Nangdo and served under Hwarang Yu Sin (one of the knights), before being discovered as the princess.
That was the starting point of her struggle for power against Mi Shil who have been vying for the throne for decades.

There's also the sad love story of Princess Deok Man when she became the reigning Queen and Bi-dam (Kim Nam Gil), the only guy whom she could lean on.
