A young woman is suddenly drawn into a world of demon hunting by a total stranger. The stranger is convinced that like him, she can identify people who are possessed by demons, drive them out of the person's body and save the persons soul. In order to do this she must look into the persons eyes where she will understand if the person is possessed or not. She will be able to see deep inside the person and determine if they are possessed or not, because the eyes are windows to the soul.
