Soo Jin is quite a cold-hearted woman who studies birds, which are her only interested. She doesn't like children, but she has to work as an elementary teacher for a few weeks. A girl named Hye Na in her class catches Soo Jin's attention, and she starts to worry about her because the child doesn't seem to be taken good care of by her family. Before Soo Jin quits the school, she goes to Hye Na's house to say goodbye, but she is terrified to see something shocking there.
