The film opens in a bleak police station where celebrated war correspondent Kate Rafter (Seagrove) faces questions from a psychiatrist, Dr Shaw (Kurylenko), as they work through the painful events of Rafter’s life. A horrific incident in war-torn Iraq and the death of her mother (Steed) have brought a haunted Rafter home to Herne Bay, a place she believed she had escaped forever. Her resentful sister (Friel) has not made her sister welcome and her forbearing husband Paul (Miles) fails to broker peace. Whilst packing up her mother’s belongings from her childhood home, Rafter comes to believe there is something strange and terrifying happening in the house next door.
