The 7th Day

"Yeon-Hee (Ko Eun-Mi) works as a nurse at a hospital. On a rainy night, a man with the appearance of a doctor enters the room of female patient with hemorrhoids. He informs her that he will take pictures of her injured area. The next day, the woman informs the hospital about the strange late night visit. Executives of the hospital knows something is wrong and they want to find the person impersonating the doctor discreetly before it becomes public. They order Yeon-Hee to find who that person is."
