Sympathy for Mr. Vengeance (2005)

Synopsis
Korean director Park Chan-wook followed up his highly acclaimed Joint Security Area with this tale of a deaf mute named Ryu (Shin Ha-kyun) trying to help his sister (Lim Ji-Eun) get a kidney transplant. Because his blood type is incompatible and no donors are available, he turns to a group of black-market organ dealers who offer to find one in return for one of his and ten million won. The dealers rip him off, so Ryu conspires with his girlfriend, a political activist, to kidnap his former boss' young daughter and ransom her for the ten million won. But a horrible complication ruins their plans and things begin to spiral out of control as the girl's father (Song Kang-ho) decides to take matters into his own hands with the help of a sympathetic cop. ~ Tom Vick, All Movie Guide
