Fourteen-year-old Abi lives with her mother and brother in central London. She has problems at school, a strained relationship with her mother and she is also having trouble sleeping due to the strange noises coming from the flat above her. She can hear her neighbours beating each other. Her neighbour Rita is a big and imposing woman who lives with her small husband in the flat above. Abi jokes that Rita beats her husband but is not sure what she really believes is happening upstairs or what she hears late at night. One morning Abi finds herself in Rita’s flat and realizes that the truth is very different from her assumptions.
