Seobok is a South Korean science fiction film directed by Lee Yong-ju. The movie follows former intelligence agent Min Ki-heon (played by Gong Yoo), who is diagnosed with terminal cancer and given only a few months to live. His former employer, the National Intelligence Service (NIS), approaches him with an offer to provide him with a cure for his cancer in exchange for retrieving the first-ever human clone, Seobok (played by Park Bo-gum).
Seobok is a genetically engineered being with cells that are believed to hold the key to eternal life. The NIS wants to use Seobok's cells for research purposes, but there are others who are also after Seobok. As Ki-heon and Seobok begin their journey, they encounter a variety of obstacles as they try to avoid the people who are pursuing Seobok.
The movie explores themes of mortality, ethics, and the dangers of genetic modification. At the heart of the film is the relationship between Ki-heon and Seobok. Ki-heon is initially hesitant to take on the mission, but he soon grows attached to Seobok and begins to see him as a real person rather than just a means to an end.
As the two become closer, Ki-heon realizes that Seobok is not just a scientific experiment but a sentient being with his own thoughts and emotions. The bond between Ki-heon and Seobok is tested as they navigate their way through a dangerous world where both the NIS and a powerful conglomerate are after Seobok.
Overall, Seobok is a thrilling and thought-provoking movie that explores complex ethical questions in the context of a fast-paced and action-packed narrative.
