The Classified File (2015 Film)
The Classified File (Korean: 극비수사; RR: Keukbisoosa) is a 2015 South Korean crime drama directed by Kwak Kyung-taek. Set in 1978, the film dramatizes the true story of a high-profile kidnapping case involving a child from a wealthy family in Busan.

Plot
When a young girl named Eun-joo is kidnapped, her family struggles to find help as the kidnapper remains silent. Seeking answers, the mother and aunt consult various fortunetellers. Kim Joong-san (Yu Hae-jin), a fortuneteller, is the only one who insists that the girl is still alive. He advises the family to seek the assistance of Detective Kong Gil-yong (Kim Yun-seok).
Although initially skeptical, Detective Kong agrees to take the case. He emphasizes the need for absolute secrecy to ensure the child's safety. As the investigation progresses, Kim Joong-san's predictions prove accurate, including the timing of the kidnapper's contact. The collaboration between the detective and the fortuneteller becomes the central focus of the investigation.
