About the title
A crime drama about two very different police officers who together investigate a major case that shook the entire police organization. Min Jae (Choi Woo-shik) — an officer from a family of policemen — is ordered to secretly investigate the case of Kang Yoon (Cho Jin-woong), the top head of the investigation team. Min Jae is convinced: "If a police officer does something illegal, even if it happens during an investigation, he is a criminal too." But as Min Jae investigates Kang Yoon's case, he himself begins to resemble Kang Yoon, who believes that "pursuing a criminal is justified, even if it's illegal." Will Min Jae be able to carry out his mission and arrest Kang Yoon, whom he trusts and admires?
