Following the hugely successful Oldboy, Lady Vengeance is another showcase for the extraordinary talents of Park Chan-wook.

Lee Guem-ja has been released from jail having served 13 years for the kidnapping and murder of a child. A seemingly unassuming prisoner, Guem-ja has in fact been plotting her revenge on the man who was responsible for her incarceration. With the help of some of her fellow inmates her plan will soon be complete. But, just as her trap is ready, Guem-ja finds herself re-united with her long lost daughter.

Will her daughter be able to bring her the peace she so desires and will her long committed quest for revenge lead to salvation or damnation?
