10 years ago, the mafia family Three-J welcomed into their family Dae-suh, the graduate of a prestigious university and a successful entrepreneur. 10 years later, the Three-J clan leaves their calling as a mafia family and takes a sound path in life, establishing construction company. However, the circle of trust is breached when Dae-suh, and not the three brothers of Three-J clan, becomes the president of the company. Threatened that he might take over the entire company later on, the three brothers plot an conspiracy against Dae-suh, just like 10 years ago when they tried to get Dae-suh to marry their sister.
