provide sex and assist in his kidnapping racket in return. He used her to lure 5-year-old Won-mo to him, with the intent of ransoming the child, but murdered the boy. He then kidnapped Geum-ja's infant daughter and threatened to murder the baby if Geum-ja did not take the blame. She has spent her time in prison planning revenge on Mr. Baek for the murder of Won-mo, causing Geum-ja's child to grow up without a mother, and for sending her to prison. Geum-ja discovers that her daughter was adopted by Australian parents. Jenny, now an adolescent, does not speak Korean and does not initially embrace her mother, though she does return with Geum-ja to Seoul to bond.

They then bury the corpse outside. Geum-ja, the detective, and the relatives all converge at Geum-ja's bakery. Afterward, she sees the ghost of the murdered child who then transforms into his grown self (the age that he would have been if he had lived). Later, she meets Jenny and instructs
