老手2

侦探徐道哲(黄正民)和他的重大犯罪调查部门不知疲倦地日夜追踪罪犯，经常以牺牲他们的个人生活为代价。 当一名教授的谋杀案揭示了与过去案件的联系时，对连环杀手的怀疑出现了，使国家陷入动荡。随着重案组的深入调查，凶手通过在网上公开发布预告片来嘲弄他们，指出下一个受害者，并加剧了混乱。 为了应对不断升级的威胁，该团队引入了理想主义的新秀警官Park Sun-woo (JUNG Hae-in)，导致案件的发展轨迹出现意想不到的转折。

Detective Seo Do-cheol (HWANG Jung-min) and his Major Crime Investigation Division tirelessly track down criminals day and night, often at the expense of their personal lives.

When the murder of a professor reveals links to past cases, suspicions of a serial killer arise, plunging the country into turmoil. As Major Crimes delves into the investigation, the killer taunts them by publicly releasing a teaser online, indicating the next victim, and intensifying the chaos.

To tackle the escalating threat, the team brings in idealistic rookie officer Park Sun-woo (JUNG Hae-in), leading to unexpected twists in the case’s trajectory.
