Namgoong Min became a reporter to avenge his brother's death but he was tricked by Moon Sung-keun.
Han Moo-yeong (Namgoong Min) wanted to find out the truth behind his brother Han Cheol-ho's (Oh Jeong-se) death.
Five years ago, Lee Seok-min (Yoo Joon-sang) and investigator Kwon So-ra (Eom Ji-won) were investigating a case on secret funds when Koo Tae-won (Moon Sung-keun) hit them in the back of their heads. Seok-min was demoted and so was So-ra. Cheol-ho, who wrote the report, suddenly died from an accident.
