The Policeman\'s Lineage

Like his father and grandfather, Min Jae is also a cop. This time, he has been ordered to secretly investigate his superior Kang Yoon, who is the team leader of an investigation team that he has been assigned to. Min Jae upholds and follows the law stringently, while Kang Yoon adheres to the principle that the end will justify the means, even if he has to do something illegal to achieve it. As the two officers work closely together, Mon Jae begins to trust and admire Kang Yoon, but he is now torn between his mission and duty, and doing what he now thinks is the right thing.
