Robert Miller, a veteran paratrooper, is returning from the war in Afghanistan to his home in a violent decaying South LondonHeygate Estate, overrun by gun-toting youth gangs. The gangs are led by a drug lord gangster Jones who is interested in Miller working for him, but his job offer is rejected.
Through an ex-army mate, Miller finds work in undercover surveillance. He is soon recruited by a couple of shady government operatives for an undercover operation to keep tabs on a network of suspected terrorist cells. Embedded in the terrorist group is a Lebanese-born British citizen informant.
Miller soon discovers that the security forces and the intelligence services are not quite what they seem. He uncovers a conspiracy the government is planning to set off a series of coordinated attacks to renew fear of terrorism to help them benefit from the GOD policy - Guns, Oil, and Drugs. Miller finds out that all his surveillance was simply to confirm the go-ahead for the attacks. The government needs funding and the GOD policy has been instated for years. Miller finds out that this links with the local gang terrorising his neighbourhood being linked with the terrorist cells.
Miller attacks and kills most of Jones' men, but also accidentally shoots an innocent woman. He ends up being shot dead by a young kid that Miller had previously been trying to get out of Jones' gang.
