Yi Eon manages to capture one of Mal Jong's men, who were chasing Jo Yi, and gets a clue about their hideout. They plan to barge into it to find more evidence about Bo Ri's death and the account book. Meanwhile, Do Soo is also curious to know where Tae Seo gets his expenses and decides to visit his hideout himself.

However, he gets shocked after he sees the dead body of Seok Gi on the ground and figures out someone else is going after Tae Seo as well. Meanwhile, Bi Ryeong has no choice but to help Do Soo find Tae Seo's mine, where he has set up poisonous traps.
