The film is about a family in crime-ridden Hackney, East London, the eldest son's involvement in gun crime, and the effects of this on his younger brother.
Upon being released from prison, Ricky (Ashley Walters) is collected by Wisdom, an eccentric and naive friend who is desperate to establish himself within their neighbourhood.
Immediately after arriving back, Wisdom accidentally breaks a wing mirror off a car belonging to Godfrey, a local gang member.
As a result, Godfrey and his associate destroy Wisdom's car with a baseball bat and drive past his home shouting that he is "dead."
Their mother when she next sees Ricky, asks him to go home, pack his belongings and leave whilst they are at church to give Curtis a chance to avoid the gang lifestyle.
