Han Gong Ju is a young school girl who is suddenly up rooted from her home and taken to a new district to live and attend a new school. All we know is that there has been 'a scandal' at her old school and that she was directly involved. Her school teacher takes her to live with his mother - who runs a little supermarket.
Han Gong Ju then tries to rebuild a life devoid of the past, but her curious detachment acts as a lure for some of her new class mates and try as she might the past always has a strange way of catching up with us.
This is probably a slow burner, but the direction and pacing make it feel more immediate than it actually is. The performances are all sufficiently nuanced to keep one guessing as to what really happened and as such the past is done in a slow reveal through flash backs. The back story could have been fleshed out better but once gain we have enough hints and subtle asides that help put all the pieces together. This is one where your full attention is required, but that is quite easy as it is very gripping. Another great piece of cinema from South Korea.
