One day, Hwa Young (Lee Seong Yeon, 3-iron) receives a mysterious parcel labeled “So Hwa 20 Years”. In it, she finds an official death notice and some personal belongings of a Japanese soldier. A photo displaying the deceased soldier and a woman catches her attention. The woman on the photo looks just like her! Terrified, Hwa Young throws out the package, but a few days later, the same package reappears.
