Dianne and Luke move into their grandmother's mansion that had stood more than 70 years; thinking they are safer over there... But they jinxed it. After one night, grandmother dies and the 10 year olds are curious. Everyone says that she died of her life timer,(old aged) but the kid's say every breathing, moving, living thing with a weapon is a suspect. The suspect turns out to be a killer... That can never leave her mansion.
