She was hired to take care of an old woman with limited mobility in a haunted house. The clumsy Cindy did bad things with good intentions, causing the old woman to suffer from disasters. And this haunted house is by no means a false name. A boy whose ghost remains alive after being killed appears from time to time, hoping that Cindy will help him find the real murderer. Next to the house lives failed father Tom Ryan (Craig Bierko), who is spending the weekend with his children. After a series of conversations, Tom and Cindy fell in love. At this time, terrifying aliens invaded the earth, and they wanted to completely eliminate mankind. How can Cindy and Tom escape?
