After his father's passing at the hand of Gaya Hotel Group, Han Yi Soo (Kim Nam Gil) has lived for starters only: Vengeance. Willing to hatch a plan to bring his nemesis once and for all, Yi Soo goes in not changing his face, but in addition his identity. But there exists a massive obstacle in Yi Soo's way: his inconvenient love for Jo Hae Woo (Son Ye Jin), the heiress to Gaya Hotel Group. Along with being enmeshed in an unlucky love, Yi Soo's cover gets discounted, that includes him running for his life like his father once did. You either sink or you swim, but what if the water is high in sharks?
