Yoo Seung Ho (Remember), Kim So Hyun (Goblin: The Great and Lonely God, Let’s Fight Ghost), L (Kim Myung Soo from INFINITE and Sly and Single Again) and Yoon So Hee (Bong Soon - A Cyborg in Love) star in a historical drama about a man who wages a lone war against an evil larger than anything the dynasty has faced. When a Crown Prince realizes that his people are suffering at the hands of an organization even he can’t stop, he takes a stand and destroys them from the shadows.
The stage is the 18th century Korea. The Joseon Dynasty has been going strong for four centuries. The Crown Prince Lee Sun (Yoo Seung Ho) is a strong and just man. He should be the ruler of everything. But he isn’t. The Pyunsoo Hwe aren’t just an organization with money; they are the de facto rulers of the country. By privatizing the water supply in Joseon, they have accumulated massive amounts of wealth, power and political clout. They are led by the villainous Dae Mok (Heo Joon Ho from Beautiful Mind), a seemingly warm and kind man who harbors evil beyond most people’s wildest imaginations.
In name, there is a monarchy. In reality, the Pyunsoo Hwe pull the strings. Even the Crown Prince cannot openly fight them. But Lee Sun is the last hope of the people suffering under the dark hand of the Pyunsoo Hwe. And he isn’t planning on backing down.
Han Ga Eun (Kim So Hyun) is the woman the Crown Prince loves. The daughter of a military family, Han Ga Eun is extremely intelligent. She also has a strong sense of justice and is super unladylike. She also wants to take revenge on the Crown Prince for beheading her father. Instead, she falls in love with him, helps him grow as a ruler, and serves as his confidant in a world filled with betrayal.
Lee Sun (L) is a commoner and the son of a butcher. Oddly enough, he is also somewhat the new king. He once used to believe that his life was worth nothing. In spite of his massive intelligence, he drifted away and lived a meaningless existence. Until Han Ga Eun taught him to read. Now, he is a stand-in for the king. A faker designed to distract from what the real king is doing in the shadows. And while he is incredibly intelligent and passionate, even he has a tough time being the target of the Crown Prince’s many enemies.
Kim Hwa Goon (Yoon So Hee) is the granddaughter of the head of the Pyunsoo Hwe. She is used to getting whatever she wants and thinks the prince is a weak man who lives behind a mask. She has lived a tragic life, and she is supposed to be the Crown Prince’s most dangerous opponent -- until she falls in love with him. Now, she must either fight for her family, or throw away everything and betray them to love the Prince.
And while he struggles to destroy the Pyunsoo Hwe, the Crown Prince also has a personal mystery to solve. When he was young, he was given a strange mask. He has lived behind that mask forever, and the only man who knows why is Woo Bo (Park Chul Min from Moonlight Drawn by Clouds), an old teacher of the prince’s. He now lives as an exiled noble, and holds the key to the prince’s childhood dilemma. Can the crown prince stop an organization so ruthless, so powerful and so invincible? And what is the secret behind the mask?
