Kim Seon-dal and his crew—Bo-won, the master of disguise, Yoon Bo-sal, the fake Shaman, and young and innocent Gyeon-yi— are a group of notorious con-artists in Joseon. They travel around Joseon, pulling tricks that leave even their victims amazed at their skills. However, the plan to steal Dampago tobacco goes wrong, and they suffer irreversible loss. Seon-dal learns that Seong Dae-ryeon, the most powerful politician of the time, was behind what happened and swears to take revenge. Their plan is none other than selling Daedong River to swindle Seong Dae-ryeon out of everything he owns.
