Who's there?

Through Sue's blog, a young woman begs Ellen and her friends for help with a log cabin she recently inherited. Situated deep in the San Juan mountains and in pristine condition, the Colorado cabin looks like a paradise, especially in winter when it's surrounded by snow-covered fir and cypress trees. But there's an unwanted presence that has turned the cabin into a living hell for the young woman and her family. Ellen, Sue, and Tanya agree to "clean house" only to find themselves lured into a hell they didn't know existed.

How will Ellen and her friends get out of this one?
