Kim So sun is a secret agent of the Communist Party of Korea. It was precisely because of the money attack by action group member Lin that she became a member of the party. The goal of prosecutor Oh Je Do of the Special Investigation Bureau is to surround the Communist Party by arresting Su San. Jin Susan attempted suicide, but was unsuccessful because she was a two faced person. She was once again deceived by Lin's sweet words and then ordered to assassinate Prosecutor Wu. Soon, she will take the action to be revealed later. The secrets of the Communist Party were exposed and they were arrested by the Special Investigation Bureau.
