Having buried her husband recently, emotionally scarred, grief-stricken high-school teacher Beth returns to the spacious, eerily vacant lake house he built for her in the heart of a gloomy forest. But as pained Beth tries to pick up the pieces, before long, mysterious shadows and blood-curdling reflections on the windows start to taunt her, and suddenly, she finds herself opening boxes, rummaging through the deceased's belongings. And little by little, Beth's intense late-night nightmares become increasingly vivid, taking a toll on her already fragile sanity. Now, pressing questions demand clear answers. Will Beth ever unearth the secret of the night house?
