Sea Fog is a 2014 South Korean crime thriller film directed by Shim Sung-bo. The film is adapted from the 2007 stage play Haemoo, which in turn was based on the true story of 25 Korean-Chinese illegal immigrants who suffocated to death in the storage tank of the fishing vessel Taechangho; their bodies were dumped by the ship's crew into the sea southwest of Yeosu on October 7, 2001. The original play, written by Kim Min Jeong and directed by Ahn Kyung-mo, was performed in 2007 as part of Yeonwoo Stage's 30th anniversary celebration.
