Blood Rain (film)

Blood Rain Hangul RRHyeolui Nu is a 2005 South Korean film. A murder mystery set in 1808, the film touches on historical prejudice against Roman Catholicism in the Joseon Dynasty. Although primarily a period thriller, director Kim Daeseung weaves together an unconventional mix of stylesa puzzlebox mystery plot traditionally associated with detective fiction, classconscious social commentary, lush cinematography, sets and costume design, and a flair for gore.

This isolated and largely autonomous island begins to be plagued by a string of gruesome murders. However, its not just the mounting death toll thats causing residents to worry, but the sadistic, methodical way in which the victims were killed. With the killer still on the loose, the government sends in special investigator Wonkyu to crack the case. While conducting his dogged investigation, he soon uncovers a myriad of hidden secrets, tracing the murders back to an incident that occurred some seven years earlier, in which the former owner of the mill was executed for practicing Catholicism. The townspeople, for their part, are convinced that the dead mans ghost has come back for revenge. As the young officer digs deeper into the islands dark past, Wonkyu discovers that there may be something even more frightening than the murders or the murderera truth that will make him question the depths of human nature.
