This is a thriller, directed by Lee Eon-Hee. The film is really good.

Ji-sun’s daily life is hell, she is working in TV series marketing and also is undergoing a custody battle for her 18-month old daughter Da-eun. Ji-Sun hires a nanny Han-mae. The baby and the Nanny get along really well. One day, When Ji-sun gets back from work, she finds out both her Nanny and the baby disappeared. Thus, begins her searching.

I really loved the movie. I got no words for Gong Hyo-jin and Uhm Ji-won's acting! Mind-blowing. The story is well written.
