Spero Lucas, a 29-year-old veteran of the war in Iraq, is now a private investigator for a defence attorney in Washington DC. When a jailed marijuana dealer asks him to retrieve two stolen consignments, Lucas agrees - for a 40 per cent cut of the proceeds. However, when two of the dealer's young lieutenants are shot in the face, Lucas finds himself in a situation which calls on all the lethal skills he learned in the alleyways of Fallujah.
