Libera Me (2000)

A firefighter starts playing detective in his spare time to bring down a psychotic arsonist in this thriller. Hee-su (Cha Seung-weon) is a man with a dangerous obsession; having served a long prison sentence for arson, Hee-su has not only failed to change his ways, but is returning to his firebug ways with a vengeance, even torching his cell with a remote device on the day of his release. Hee-su starts out relatively small but soon begins lighting up bigger and more important targets, and as he starts deadly fires that claim lives at a local hospital, dedicated fireman Sang-woo (Choi Min-su) makes it his mission to bring Hee-su to justice. Libera Me proved to be a popular breakthrough for director Yang Yun-ho, who is better known for more serious fare.
