The drama is about Crown Prince Lee Sun (Yoo Seung Ho), who fights against members of a corrupt organization who want to privatize the nation’s water supply for their own personal gain. The Crown Prince has to hide behind a mask, for reasons that are still unclear, and attempts to use this to his advantage by trading places with a brilliant but lowly commoner of the same name, who is played by INFINITE’s L (Kim Myung Soo). The two both fall in love with the same girl, Han Ga Eun (Kim So Hyun), complicating their inextricably linked fates even further.
