When her boyfriend Ben suddenly dies in an accident, mother-to-be Charlotte collapses upon receiving the news. She wakes up in Ben’s family home, a crumbling old manor house in the middle of nowhere with Ben’s overbearing mother, Margaret, and his controlling stepbrother, Thomas. They are determined to care for her, at least until the baby arrives. Grief stricken and increasingly haunted by visions possibly brought on by the pregnancy, Charlotte accepts their help. But as the days go by she begins to doubt their intentions and her suspicions grow. Are they drugging her and keeping her captive, with the aim of taking her unborn baby? As her visions intensify and the haze of lies grows, Charlotte decides that her only option is to break free from this family once and for all – but at what cost?
