Kate lives in a suburban street with her 18 year old daughter Chloe. She has always maintained that Chloe has learning difficulties. She runs a business from home and receives maintenance from her ex-husband, who Chloe goes to visit regularly. Chloe is best friends with Bethany who lives across the street, but who is a few years younger. Her family are heaving involved in the Church.

One day Chloe returns unexpectedly early from a visit to her father's. Bethany's father sees her at the train station and brings her home, for them both to find Kate missing and the house full of blood.
