Actress Han Hyo Joo flaunts her pure charm through her character poster for film 'Masquerade.'

'Masquerade' is a film about Chosun's King Kwang Hae on the brink of being poisoned and the episodes that follow low-class Ha Sun disguising himself as the king. It is the hidden story of a 15-day period that has vanished from history.

Han Hyo Joo plays the main female character, the queen in the midst of the secret between the real king and fake king. In the recently revealed poster, Han Hyo Joo captures the attention of audiences with her elegant image and tear-swallowing expression. The caption, "I prayed every night to not be born a woman of the palace in my next life," is also raising the curiosity of fans.

In this film, actor Lee Byung Hun will play two roles as the king and a man of low class, while Ryu Seung Ryong will play the man responsible for arranging the secret switch between the two.

'A man who shouldn't be a king becomes the king of Chosun,' film 'Masquerade' stars Lee Byung Hun, Han Hyo Joo, and Ryu Seung Ryong.

'Masquerade' will be released in theaters in September.
