"The final installment of director Park Chan-wook's revenge trilogy (preceded by Sympathy for Mr. Vengeance and Oldboy) chronicles the efforts of Lee Geum-ja (Lee Yeong-ae) -- known to her cellmates as "the kind Ms. Geum-ja" -- to track down the man who betrayed her. Taking the rap for her accomplice and incarcerated for 13 long years, she plots an elaborate retribution with help from her fellow inmates. "

Watched this last night. It's a good film, not as hardcore as Oldboy. There are a few scenes that are slow.. but over all, a film worth checking out.
