When her elderly mother is hospitalized unexpectedly, Vicki travels to her parents' isolated ranch home in Alberta, Canada, to help her father. She has been estranged from her parents for many years (the reasons for which rapidly become clear) and is horrified by what she discovers on her arrival. Her mother has always been mentally unstable, but for years camouflaged her delusions and unpredictability. Over the decades she has managed to shut herself and her husband away from the outside world. Vicki's father, who has been systematically starved and kept virtually a prisoner in his own home, begins to realize what has happened to him and embarks upon plans of his own to combat his wife. Vicki quickly realizes how dangerous, and potentially life-threatening, her mother's behavior is. She fears for her father's life and her own safety if her mother returns home. The power play between her parents takes a dramatic turn and leaves Vicki embroiled in situations that are ludicrous, heart-breaking, and frightening.
