Upon receiving a terminal diagnosis, Sarah opts for a cloning procedure to ease her loss to her friends and family. When she makes a sudden and miraculous recovery, her attempts to have her clone decommissioned fail and lead to a court-mandated duel to the death.

Residents of an isolated, high-tech compound discover they are actually clones--and worth more dead than alive--but after they stage a daring escape, they must face an unfamiliar environment and an armed team of mercenaries in hot pursuit, and jeopardize everything to save those they left behind and reveal the truth about The Island.

Min Ki-Hun, a former intelligence agent, is given secret orders to transport the first ever human clone, Seobok, from his life in a lab to a new safe location. Because the robotic clone holds the secret to immortality, evil organizations try to kidnap him and extract that secret. After the duo escapes, Ki-Hun will do everything in his power to shield and protect Seobok from those groups with hidden agendas and bad intentions.
