The Dark Harbor Lighthouse, abandoned by Sheriff Wilde after his wife's mysterious disappearance, sat empty for over ten years. Now the Hanson family has moved in, but before long, strange things begin to happen in their dream house: lit candles in the windows, eerie music from the piano room, moving furniture, and a shadowy figure who walks the lighthouse tower at midnight. As Raven, the disaffected teenage daughter, and Ethan, a next-door neighbor, try to discover what dark secrets Aunt Rosemary is keeping and the true identity of little Penny's imaginary friend, they unknowingly place themselves directly in the path of the recently awakened and vengeful Silver Lady. As deception after deception is revealed, the two friends race against the clock to prevent another grisly murder from occurring.
