In "Hidden Identity" Lee Won Jong rescued the Investigations - 5 team. In the past, the Investigations - 5 team had been placed in a risky situation because of a person that had been acting like he was possessed.
On the 3rd episode of tvN Monday/Tuesday drama "Hidden Identity" broadcast on June 22nd, Teacher Jung (played by Kim Min Joon) and his group, started to go up against the police.
On this day, the people infiltrated the house to hack the hologram program code. These people were so busy that they did not recognize that Gun Woo (played by Beom) was undercover. Moo Won (played by Park Sung Woon) was waiting outside the building and started to officially move. Afterwards, he started to move inside the building.
Afterwards, he asked to the masked people. "The people responsible for this are the police. What do you want.'" Afterwards, they tried to attempt a negotiation and showed Tae Pyong (played by Lee Won Jong) how to make an attempt by giving him a hint.
Tae Pyong who received a signal started to act hurt. He asked a person in the masked gang to give him a thermos with medicine. As soon as he tried to open the thermos, the bottle exploded and there was gas oozing out to fill the building.
