Plot Summary

Kim Bu-jang appears to be nothing more than a humble employee working at a small savings bank. To everyone aroundhim, he is a quiet, hardworking single father who dedicates his life to raising his daughter, Min-ji. He avoids trouble, keeps to himself, and lives an ordinary life.

But appearances can be deceiving.

Long before becoming an office worker, Kim Bu-jang was one of the most feared covert agents in the country. He completed countless classified missions and survived dangerous operations that few people even knew existed. His name eventually landed on North Korea’s most wanted list, forcing him to erase his past and disappear into civilian life.

His peaceful world comes crashing down when Min-ji suddenly vanishes without a trace.

With the police unable to uncover the truth, Kim realizes he has only one option—to become the deadly operative he once was. As he races against time, he reunites with former allies, battles ruthless enemies, and uncovers a conspiracy far larger than a simple kidnapping.

Every fight pushes him closer to the truth while forcing him to confront the painful past he tried so desperately to leave behind. The drama masterfully balances explosive action with emotional moments, making viewers care just as much about Kim’s relationship with his daughter as they do about the thrilling rescue mission.
