Summer Reynolds is a beautiful, successful and caring woman who is working the job that she has dreamed of since she was a child. She never imaged that being a nurse would turn into a nightmare. She starts to experience things that she cannot explain and feels as though she may be on the edge of a breakdown.

One frigid November evening as she is driving home the unimaginable happened. Summer now must figure out a way to get herself out the scary situation she has been put in.
