Meredith moves to the Langrock estate to take care of Langrock himself, an ailing man whose legs no longer work. Langrock has a son who is disturbed in some way, as well as his orphaned teenage grandson Gabriel who returns from a desert commune (or something) to live with the family. Langrock's butler has been working his way through the wine cellar for years, and the cook is proud of her granola...mmm.
Gabriel is a strange young man who likes lurking in shadows, saying or reacting in peculiar ways and generally making people uneasy. Meredith is fascinated by him, but also fears he's behind the brutal death of the guard dog and the other deaths that follow.
A fair amount of the movie also has voice-over by Meredith.
The Embassy Home Entertainment VHS is not the best print; nighttime scenes or those in the cellar are dark and lack definition. The end credits are fairly unreadable.
