Karen, recently divorced, returns to her childhood home in Nova Scotia after her mother’s death, to care for her developmentally-disabled sister. Karen is understandably over-whelmed with grief and the difficult care of her sister. Thus she gratefully accepts extra assistance from Trevor, one of her sisters care-givers. So she is susceptible to manipulation and Trevor is a master manipulator. Accordingly, this is a masterful and entirely creepy character study of human frailty.
