In the 14th episode of the SBS Friday-Saturday drama 'Taxi Driver 3,' which aired on the 3rd, the Rainbow Heroes were depicted taking down the villains of Samheungdo. In this episode, it was revealed that the crime planner Ko Jang-gak was a former prosecutor. Ko Jang-gak was connected to the criminals of Samheungdo, who were offenders he had encountered during his time as a prosecutor. They gathered in Samheungdo to plan and execute their crimes.

Kim Do-ki, Jang Sung-chul, Ahn Go-eun, Chief Choi, and Chief Park initiated their operation. Kim Do-ki met with Ko Jang-gak alone and requested him to deal with Jang Sung-chul. He said, "Before starting the job, there's something to resolve. It's about taking care of the representative who came with me." Jang Sung-chul also asked Seo Hwang to kill Kim Do-ki, stating, "I'm older and have more money, yet he thinks he's the boss," and offered a reward.

Ahn Go-eun told Ko Jang-gak, "From what I hear, there's no need for many people. Throw that guy into the sea where no one can find him," requesting to kill Kim Do-ki. They expressed their requests to kill each other, creating a sense of bewilderment. Ko Jang-gak remarked, "I think it's time to move," planning to eliminate the Rainbow Heroes and relocate elsewhere.

The Rainbow Heroes began to act decisively. Ahn Go-eun captured Ko Jang-gak, Seo Hwang, and Madam Yeo according to her plan to hack into the crime planning server. This led to Ahn Go-eun successfully shutting down the server. Ko Jang-gak noticed the Rainbow Heroes' intentions and called Kim Do-ki in anger, asking, "What's the reason you're going this far?"
