During a total solar eclipse, Go Ha-jin (Lee Ji-eun) plunges into the water and emerges from its inky depths in the year 941, with a completely new identity, Hae Soo. There she meets the many royal princes of the ruling Wang family and bears witness to the complexities of their relationships with one another and others.
Positioned in the house of the 8th Prince Wang Wook (Kang Ha-neul), she starts to develop feelings for him, but a series of events drives (and keeps them apart). Then she meets the mysterious and masked Wang So (Lee Joon-gi) and her life is turned upside down, as he ushers her into an epic adventure filled with drama, suspense, intrigue and romance.
