Karen goes into a Japanese house as a substitute nurse to Emma, a strange woman who sleeps at day and wakes at night. Karen goes upstairs after hearing noises when she encounters a frightening ghost. She will learn the house's secrets.

It is very scary! The scenes are shocking and frightening! The characters are good. The settings are creepy. I love the whole plot! The ending was shocking! I paused at a scene where the little boy meowed so loudly to the man finding his sister upstairs and I was shocked. This is the scariest movie I have watched. I did not see the Japanese version. I recommend this to horror fans. 10/10 and 5 stars!
