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