In the midst of money and power comes murder, deceit and lies.

Choi Seung Hyun ,The most powerful man in Korea, falls sick and needs one of his 4 sons to take over his company.

Will the company go to the eldest son, Choi Park Kris; An obsessive playboy that has an appetite for control and jealousy.

Or will it go to the second eldest son, Choi Park Chanyeol; An overly erted, struggling alcoholic with a cold demeanour and aching sorrow.

Or to the youngest brothers of the family, the twins, Choi Wen Sehun and Choi Wen Kai ; Kai-, a spoiled, father hating jock that only looks out for himself until he meets the love of his life. Sehun; the nicest of the Choi's, with an eye for all things nice including ty maids, his hyung's lovers and grapes.

Choi signs a merging deal with the owner of Kwon Industries, Kwon Ji-Yong. Seung also decides to arrange a marriage, without his sons knowledge or consent, to two of Ji-Yongs sons, Kwon Tao and Kwon DO.

The household also gets three new additions to their package. The new maid: Kim Baekhyun and their two long lost uncles, Choi Seung Cheol and Choi Minsoek. Two of the new guests hold deadly intentions/secrets and one of new guests holds a secret, without his knowledge, that could bring the empire to shreds. And one maid, Chen, vows to get his Yeollie at whatever costs. Dead or alive.

Is everyone who they say they are or do venomous snakes slither among them?
