Skunk and his team successfully steal the Joseon Tongbo coin at Jang Chun Fung's hotel according to the plan. However, Viper appears out of nowhere to ruin it as if he knows their location. Meanwhile, Young-soo desperately waits for the fated moment to come, and Ae-ri gets into Dae-myung's room at the hotel and finds Skunk's mask.

Team Karma safely returns from Jeju Island and looks into traps in Young-soo's secret vault in the training facility of Mugunghwa Foundation. However, they cannot get a signal to it even with the GPS tracker on the fake Joseon Tongbo coin. Meanwhile, Ae-ri joins Team Karma, and her first mission is to get Young-soo's fingerprint.

Skunk and Min-woo manage to get inside Young-soo's maze. However, it is their first time sneaking into a secret vault without any information, so they have to make sure they don't get caught in his traps. Meanwhile, Young-soo knew they were planning to break in all along, and he is waiting for them to fall for his deadly trap.
