Sympathy for Lady Vengeance

Everything About Fiction You Never Wanted to Know.
Ma'am, there is no such thing as a "perfect person"...
Mr. Baek

The third film of Park Chan-wook's Vengeance Trilogy. This film's plot has parallels to both Oldboy and Sympathy for Mr. Vengeance, notably the quest for Revenge after more than a decade in confinement and the study of how vengeance can turn simple people into monsters. It is, however, very stylistically different from both installments.

Lee Geum-ja, a 19-year-old girl paying the price of some bad decisions, is blackmailed into falsely confessing to the murder of a child. After 14 years in prison, she emerges a cold, vengeance-driven woman, dropping the kind, gentle facade that had won her the friendship and loyalty of the other female prisoners.

Using her connections formed in prison, Geum-ja sets into motion a plan 14 years in the making. Her goal is to punish Mr. Baek, the real murderer; however, even Revenge may not be enough for Geum-ja to find redemption.

Tropes used in Sympathy for Lady Vengeance include:

Everyone makes mistakes. But if you committed a sin, you have to make an atonement for that sin. Atonement, do you know what that means? Big Atonement for big sins. Small Atonement for small sins.
