One man will go to any lengths to find his father’s killer. Cha Ji Won (Lee Jin Wook) is a highly trained Navy SEAL officer who is a member of the special Underwater Demolition Team. Ji Won and his best friend, Min Sun Jae (Kim Kang Woo), have done everything together since childhood, when Sun Jae was taken in by Ji Won’s father because Sun Jae wanted to get away from his deadbeat dad. But Sun Jae has always harbored a resentment against Ji Won for having a silver spoon in his mouth while he has had to struggle to get anything in life. While Ji Won’s younger sister, Cha Ji Soo (Im Se Mi), has always liked Sun Jae, Sun Jae has had a secret crush on Yoon Ma Ri (Yoo In Young), Ji Won’s fiancée. Sun Jae decides to leave the Navy to get out from under Ji Won’s shadow, but the only place he has to go is Ji Won’s father’s corporation. New on the job, Sun Jae becomes an easy target for the company’s enemies and he is framed to do a number of deeds that leads to the death of Ji Won’s father. When the devastated Ji Won learns that his father has been murdered in Thailand, he is determined to find the killer, only to find himself framed as the killer of a local man and becoming an outlaw. With the help of Korean ex-patriots Kaya (Moon Chae Won), a two-bit street hustler; Ko Sung Min (Lee Won Jong), an unlicensed doctor to local gangsters; and Kim Ji Ryoong (Kim Tae Woo), a humanitarian worker in Thailand, can Ji Won find his way back to Korea and find his father’s real killer? “Goodbye Mr. Black” is a 2016 South Korean drama series directed by Han Hee. It is based on a comic written by Hwang Mi Na that is loosely fashioned after “The Count of Monte Cristo” by Alexandre Dumas.
