Su-mi and Su-yeon have always been very close as sisters. Su-mi, being the elder of the two, is very protective over her young sister Su-yeon. Since the death of their mother, the stepmother has ruled the house with an iron fist. Su-mi has always managed to confront her stepmother, but Su-yeon, being a very calm and fragile girl, could not defend herself against the psychological and physical abuse of her evil stepmother. Su-mi has tried many times to explain the situation to her father, but his relationship with the stepmother and his disbelief has insured no result.

Su-mi and Su-yeon are now back from a mysterious absence and being back home doesn’t seem to please the two sisters very much. Having to live under the same roof as the stepmother is a nightmare for them. However, during the following days, strange incidents will occur. Another presence can be felt within the house. Is it the step mother trying to scare the girls, or a spirit trying to take revenge?
