In the episode, the character played by 김유정 becomes a secret informant after striking a deal with the character played by 김현주, and enters the Japanese Government-General as an interpreter trainee under the alias 금서희. She meets the character played by 박진영 again as a senior interpreter and makes a false confession of love to deflect his suspicion.

An assassination attempt on the character played by 진선규 by the 구국단 fails, and he orders a crackdown on the group. The character played by 김현주 proposes sending a new informant into the interpreter trainee post, choosing the character played by 김유정 for her quick wits, her skill at lying and her English, and promising to send her to America in exchange.

She completes her first mission by obtaining the schedule of the character played by 진선규 and passing it to the 구국단. At the end of the episode, an unknown person points a gun at her in a back alley, calls her a spy and puts a sack over her head.
