Kwon Man-ki's impressive debut is refreshingly different from the high-tempo thrillers South Korean cinema is known for. Low-key visuals and minimal dialogue convey the tale of Jung-je (Yoon Ji-hye, superb), an emotionally-blank cleaner. Her new workmate is Min-gu, an unsettled ex-convict. Min-gu was just a boy when Jung-je and her husband blindfolded and kidnapped him. The question of whether Min-gu will recognise his captor is just one part of Kwon's meticulously arranged screenplay. Jung-je is terrified of being exposed. She also has a desperate desire to reach out and help the troubled young man. What emerges is a suspenseful and emotionally rewarding portrait of damaged souls searching for hope.
