Now that the crime drama is almost on its half part, Kim Do Ki's true identity, played by Lee Je Hoon, is slowly being uncovered by prosecutor Kang Ha Na, portrayed by Esom. The Rainbow Taxi team has once again completed another successful mission by setting the storage of U-Data mine on fire containing illegal pornographic videos. Unfortunately, people at the Seoul Northern District Prosecutors' Office suspects that he is involved in the U-Data explosion after Do Ki's company ID was found at the crime scene by Kang Ha Na's boss, Jo Jin-Woo (Yoo Seung Mok.) After her press conference regarding the case, Prosecutor Kang Ha Na believes that someone is intervening in their case.
