About 500 years ago during the time of Chosun Dynasty, Korea boasted a rigidly hierarchical and male dominated social structure. Set in this period, "Jewel in the Palace" is based on a true story about a legendary girl (Jang Geum) who became the first woman to be the supreme royal physician of her times. Despite her poor condition as a low class girl in the male dominated society, Jang Geum overcame a series of social discrimination and landed herself as a royal cook, later becoming the royal physician, then ultimately the physician in charge of the king. She was even given by the king the title "The Great Jang Geum." The story of her checkered life on her success and breakdown as well as her love story beautifully unfold. "Jewel in the Palace" is sure to touch your heart.
