Ji-sun needs a vacation. She has a little child, she works non-stop, she has problems with his divorced husband and his mother, who want to take the child away from her... Luckily for Ji-sun, she has Han-mae, the woman that takes care of the baby while she is working. But one day, when she comes home, neither of them are there...
What follows is a thrilling and gripping thriller, full of twists and hold-your-breath moments that will keep the viewer entertained all through its running time. Things keep happening and surprises pile on top of each other. It has some plot holes, but the rhythm, acting (even if sometimes there is some overacting) and the direction more than make up for it.
The movie also includes some social criticism, as the events that unfold are based on the injustices of the societies we live in. The decisions taken by the characters make them more than black and white, and that is a strong point for the movie, as the viewer can relate and disagree with the characters and understand their motives.
