Whip Whitaker is a commuter airline pilot. While on a flight from Orlando to Atlanta something goes wrong and the plane starts to fly erratically. With little choice Whip crashes the plane and saves almost all on board. When he wakes up in the hospital, his friend from the airline union introduces him to a lawyer who tells him there's a chance he could face criminal charges because his blood test reveals that he was intoxicated with alcohol and cocaine. He denies being impaired, so while an investigation is underway, he is told to keep his act together. However, letting go of his addiction is not as easy as it seems...

Norman Spencer, a university research scientist, is growing more and more concerned about his wife, Claire, a retired concert cellist who a year ago was involved in a serious auto accident, and who has just sent off her daughter Caitlin (Norman's stepdaughter) to college. Now, Claire reports hearing voices and witnessing eerie occurrences in and around their lakeside Vermont home, including seeing the face of a young woman reflected in water. An increasingly frightened Claire thinks the phenomena have something to do with the couple living next door, especially since the wife has disappeared without apparent explanation. At her husband's urging, Claire starts to see a therapist; she tells him she thinks the house is being haunted by a ghost. His advice? Try to make contact. Enlisting the help of her best friend, Jody, and a ouija board, Claire seeks to find out the truth of What Lies Beneath.
