Her Past. Her Future. Her Family.
A teenage girl lies dead on the floor of a swimming pool. Eleven months later, Anglican priest Rebecca Ashton (Catherine McCormack) moves to Cornwall in an attempt to deal with the death of her daughter. She enjoys exploring her new environment and takes over the ministry of a local church, where she finds a Bulgarian girl, Radka (Marina Stoimenova), sleeping rough. Rebecca is compelled to mother the girl and takes over Radka's English classes at local community centre St. Piran's. The two become close and as Radka's dependence on Rebecca grows, Rebecca's motivation to help her becomes more uncertain. Reminded of her deceased daughter, Rebecca offers to become Radka's guardian but neglects to tell her she has another daughter, Eloise (Dakota Blue Richards). Ignoring Radka's jealous and volatile nature, Rebecca welcomes her into the family home where Eloise's appearance sparks a violent outburst. As the three women struggle for their lives, Rebecca is forced to come to her senses and embrace the reality of this dangerous situation.
