Samantha Cook is 36 years old, unemployed, and fresh from a year long in-patient treatment at a psychiatric clinic. Stripped of all independence and monitored 24-7 "for her own safety" by her widowed mother and an overbearing doctor, Sam resigns herself to a life without autonomy and free will, until her mother presents her with an irresistible chance - spend the summer cleaning out her late great aunt's crumbling 200 year old estate in the small beach town of Bright Bay. If she can prove herself responsible enough, she just might be granted the freedom she desperately longs for. Alone in a house that seems intent on sabotaging her at every turn, Sam begins to wonder - is the way she sees the world a weakness like she's been told, or is it just possibly her greatest strength?
