Description:

The fates of two men are crossed from the very day they're born together in the same hospital, and in turn, their families' fates as well.

Days after his younger brother's birth, Lee Dong-chul, (Song Seung-heon) witnesses the murder of his father. From then on he promises to seek revenge on the man who caused his father's death, Shin Tae-hwan (Jo Min-ki). But unbeknownst to everybody is the fact that Dong-chul's younger brother, Dong-wook (Yeon Jeong-hun), was switched at birth with Tae-hwan's son, Myeong-hun (Park Hae-jin). Dong-wook grows up to become a prosecutor and vows to help his brother seek revenge while Dong-chul chases money and power in casinos.

But what will happen when they find out that they're not brothers?

What will Dong-chul do when he finds out that his real brother was raised by Shin Tae-hwan and the brother he loves is the son of his enemy?
