The Last Witness (Korean: 흑수선; RR: Heugsuseon) is a 2001 South Korean action thriller film written and directed by Bae Chang-ho, starring Lee Jung-jae, Lee Mi-yeon, Ahn Sung-ki, and Jung Joon-ho.

Discovering a diary amongst Yang's possessions, Oh follows a trail of clues to a blind antique dealer, Ji-hye.

It transpires that it was Yang who was responsible for the imprisonment of Hwang-seok, a suspected communist sympathizer in the Korean War.

But not all is as it seems, and a series of flashbacks back to the dark days of the Korean War and the infamous Geoje POW Camp on Geojedo leads Oh to Han, a former North Korean soldier living in Japan, and a final, tragic resolution for two ill-fated lovers.
