The Law of the Line

Korean title: 라인의법칙

Synopsis

An office-politics noir set inside Nara Bank’s Seoul headquarters. Tak Do-il, a regional-university graduate with no patrons or pedigree, slips into the bank through blind recruitment and is dismissed as a so-called black tie. After cracking a voice-phishing case earns him a presidential commendation and a sudden Seoul transfer, he steps into a vicious succession war for the next bank president. Mastering every line, faction and favor, the outsider quietly turns himself into the kingmaker.
