A birthday gift takes Xiaoman, a college student, to her next step of life. She falls in love with photography and a girl. At the same time, Xiaoman starts dreaming of another unknown girl. Unsure of what she wants, Xiaoman tattoos an 'eye' on her arm to help her see through those confusing choices. However, the 'eye' leads Xiaoman to the dangerous environment the girl in her dream lives in, without her fully conscious about the process. In the darkness, the 'eye' begins to see.
