Blood Rain marks the second feature of South Korean director Kim Dae-seung (Bungee Jumping Of Their Own), and is a detective thriller set in 1808 during the Joseon Dynasty. Mysterious and deadly events are filling the residents of the remote island of Donghwa with a sense of foreboding. A local shaman (Choi Ji-na) collapses during an annual ritual, and seems momentarily possessed by the spirit of Kang (Jeon Ho-jin), a local lord who was executed. Lee Won-kyu (Cha Seung-weon) arrives from the mainland to investigate and is immediately met with a murder case. As the body count rises, Lee discovers a connection between the victims, and chillingly, to Kang himself.
