 An alienated 15 year old (Freddie Cunliffe), forced to move away from his friends in London when his family relocates to rural Devon, struggles with the change and becomes an observer of the family. His mother (Tilda Swinton) is pregnant, his dad (Ray Winstone) is vocally abusive, and his 18 year old sister (Lara Belmont) is sexually active and open to her brother. However, the boy guesses at and finds that he is correct that his father has had sexual relations with his sister. The boy gets a sexual education from an older woman (Aisling O Sullivan) he meets.
