Set in a near-distant future, a brother and sister from North London (Sarah and Dean) reunite after losing touch as teenagers. Together, they try to navigate a world in which their skin colour and social class make them feel subordinate, as well as her addiction and past abuse.  

Dean, meanwhile, is subject to an unprovoked racist attack that leaves him hospitalised. This adds fuel to an already raging fire inside him. Influenced by his friend, Piffy, he begins reading the Quran and his views become increasingly extreme.  

When Sarah is caught up in a terror attack, she grows close to fellow survivor, James, a white man whom Dean finds difficult to accept.  

Influenced by James, and her increasingly uncertain place in the world, Sarah finds herself drawn into the political world and becomes increasingly involved with UKIP, which drives a wedge between the siblings.  

When he has recovered, Dean decides to take the issue of Sarah’s past abuse into his own hands the consequences become fatal.
