A mysterious white horse, a quirky parrot, a haunted house, an ancient curse, something frightening in the attic... A summer holiday turns into a nightmare when the Mallory family rents a shabby cottage in a remote corner of Ontario's Rideau Lakes. Seventeen-year-old Chip Mallory and his sixteen-year-old sister Lee are persuaded to go along on "one last family vacation" with their parents before they get caught up in their own lives again.
