在这部双面君王剧情/古装片中,以朝鲜光海君为了逃避被毒杀的危机，便由与其相貌酷似的平民代替了王的身份为主题，讲述光海君在朝鲜历史上消失的那15天里所未人知的故事。

Joseon is in a state of disorder due to uprisings and a power struggle surrounding King Lee Hun. To avoid assassination, a clown named Ha Sun is brought to the palace to take the place of King Lee Hun. Ha Sun looks almost identical to King Lee Hun. When Ha Sun was a child, his parents died during an epidemic. Ha Sun almost died from starvation around that time, but he was saved by a group of clowns. Ha Sun grew up with the clowns and became one of them. During their performance, Ha Sun would play King Lee Hun due to their similar physical appearance. Now, Ha Sun is nervous that someone in the palace will find out he is not the real king. He falls for beautiful Queen Yoo So Woon.

这部剧颠倒了历史伦理。我的错，我不该当权谋剧看的。和影版不一样的完美。崩溃边缘！成为王的男人只为拥有王的女人？！。TVN 月火剧的新纪录？继六龙飞天后最吸引人的史剧？。只能说鸡肋吧。2019年1月韩剧清单！吕珍九弟弟新剧来袭！。严重跑题。一人分饰三角！弟弟真的太帅了【持更20190212】。中殿和珍九的选角好适合。
