Brothers Return

To avenge his brother, expose the dark forces at play, and turn around a seemingly certain death, Jin Zhen enters into a secret partnership with Zhou Yan of the Ministry of State Security. He gives up his entire identity and willingly undergoes a full suite of top-tier reconstructive surgeries, erasing every trace of Jin Zhen, the eldest son of the Beilan family. He takes on the face, bone structure, and build of his dead friend Park Cheol, and has his vocal cords subtly altered to imitate Park Cheol's hoarse, low voice.
