She left her family which consists of a dad mom and a sister to live alone is solitary place with just one couple as a neighbor and one more thing to point out is that she has not been talking to her boyfriend .so one night this intruder comes along as soon as she finds out that she is not alone it turns out to be a cat and mouse story for survival and the rest of the movie u guys have to watch have not spoiled anything...
