Since her mother’s bizarre drowning at Lake Saugus two months ago, eight-year-old Sophia Landry has been seeing the “plain people.”

They watch her. And they want her. At least, that’s what Sophia believes.

When Dr. Simon Reed tries to help the girl, he is cast into a series of events that lead him to believe not only that the plain people might be real, but that they are something much worse than even the terrified Sophia thinks they are.
