Jibaejong plot
Haunted by the memory of a terrorist attack that killed his colleagues and left the president disabled, former elite soldier Woo Chae-woon has dedicated his life to tracking down those responsible. Methodically studying the survivors of that fateful day, Chae-woon becomes even more suspicious after discovering that Yoon Ja-yu's company has made record profits in the years since the attack. With Ja-yu under constant threat of attack from drug cartels, terrorists, hackers and extremists, Chae-woon infiltrates her organization while posing as her personal bodyguard. But with attacks coming from all angles and the truth far more twisted than anyone could have imagined, will Chae-woon be able to get to the bottom of what happened that day before Ja-yu's enemies take revenge?
