Masquerade

“15 days lost to history.”

Ha-sun (Lee Byung-hun) is a commoner who performs as a clown, and all he wants is to get through each day alive. Then the court's Chief Secretary Heo-gyun (Ryu Seung-ryong) notices that Ha-sun looks exactly like King Gwanghae, who has been poisoned, and sets him on the throne in the king's place. Choo Chang-min keeps the stand-in under constant watch, and every wrong word from Ha-sun could cost him his head.
