Plot
Ji-sun is a workaholic divorced woman working at a PR Company. Her job doesn't leave her with a lot of time to spend with her 1-year-old daughter, Da-eun. Once, when her former nanny, a Chinese woman, had hit and injured Da-eun, Ji-sun had fired her but not being accustomed to taking care of her little girl, she had desperately been in need of a new nanny. Enter, Han-Mae, a young Chinese woman claiming to have a lot of experience with kids. Due to her poor conversational skills, Ji-sun had been hesitant in employing her, but when she managed to calm a crying Da-eun down within seconds, Ji-sun changed her mind and employed her immediately. She had also been entangled in a custody battle with her ex-husband, Jang Jin-hyuk, for her daughter. While her husband, a physician by profession, himself isn't too keen to have his daughter, her mother-in-law doesn't want to give up her granddaughter.
One day she received a call from her lawyer asking why she had not reached the court yet. Turns out Han-Mae had received the notice but had not mentioned it to Ji-sun, not knowing the importance of the document. She goes looking for Han-Mae to confront her about the mail, but neither she nor Da-eun are in the house. Ji-sun recalls that she had mentioned going to the clinic for Da-eun's vaccination. In the court, the judge reaches the conclusion that due to her workaholic nature and mental instability due to work and her divorce, Ji-sun had been told to hand over the girl to her in-laws months ago, but she did not abide by it. Her lawyer advises her to beg to her husband to let her keep the girl since there was no other way for her to achieve that.
On reaching home, Ji-sun finds it weird that none of the chores are done and on searching the house, Han-Mae and Da-eun are still not home. She goes around the neighbourhood, calling their names and starts becoming worried when she doesn't get any answer back. Her calls to Han-Mae also go unanswered. The security guard calls Han-Mae's protectiveness towards Da-eun peculiar. She even goes all the way to China-town to look for Han-mae, but that's a dead-end. Growing tired from all the worrying, Ji-sun falls asleep only to be woken up the next morning by her mother-in-law banging on the door. She has come to take Da-eun away. Ji-sun avoids her and heads for her car, determined to find Da-eun. She goes to the clinic that Han-Mae said she would take Da-eun to, only to find out that they had last come in 2 days ago and she had filled a prescription for a month's worth of flu medicines for the baby, something that mothers do when going on a long trip with their babies. To top it off, her neighbour's nanny, who had introduced Han-Mae to her as her niece, calls her back after getting a frantic voice-message from her. To Ji-sun's horror, she tells her that Han-Mae was not her niece and that she had paid her to introduce her in such a way. She reaches the police-station, now growing suspicious of Han-Mae. Her lawyer calls her after getting a call from her husband's lawyer, suspecting that she is trying to hide Da-Eun so her mother-in-law won't be able to take her away. He warns her of the price she would have to pay if does anything like that. Scared, she runs away from the police station not even realising that Han-Mae had forged her Foreigner Identification documents and the actual Piao Han-Mae was someone else.
She reaches home where she sees a man lurking around her flat. She grows suspicious of him when she recalls seeing him in front of her flat a few days ago as well. On confronting him, he reveals that Han-Mae owes him some money and he came here in order to get it back. She tells him that Han-Mae and her daughter have gone missing and he takes her to a Prostitution Bar in China-town, where Han-Mae used to work before. He takes her to a room where all the girls are waiting and in her paranoia, she mistakes another girl for Han-Mae and walks in on her and a customer in a room. The owner sympathises with her once she hears that her daughter is missing and promises to call her if she ever comes across or hears news of Han-Mae.
