Payback

Eun Yong, a successful investment professional retired to Mongolia, decides to fly back to Korea after he senses a threat looming over his loved ones.

Seo Yoon was a ray of light to Eun Yong, who had been living his life in darkness. She and her daughter, Joon-gyeong, were his second family to him. Eun has doubts about Yoon's death when he realises that something is not right.

Eun Yong's blood boils when he learns a detailed account of the events leading to Hye-rin's suicide; Gi-seok puts Tae-chun on the spot; Jun-gyeong is well-prepared for the revenge mission.

Eun Yong's plan to take down Chairman Myung is put into action. Joon-gyeong and Tae-chun plan on turning the situation around with a strategy of their own.

Eun Yong barely survives a life-threatening crisis. He calls on Joon-gyeong and Tae-chun to devise a new strategy. The situation takes a new turn when Joon-gyeong speaks at a press conference.

When the walls seem to close in on Eun Yong because of In-ju's sinister move, a worried and desperate Tae-chun expects Jun-gyeong to turn the situation around.
