Edwin Coker, nicknamed 'Boot', is a case officer at MI6. When a hacker falls into his hands and reveals details of a secret meeting, Boot conceives a plan to strike back - with a bomb that will seriously damage the Russian operation.
Boot turns to Merc, an ex-soldier fighting in Iraq and a gun-for-hire, to deliver the explosives into Russia and bring the hacker back. But things do not go to plan, and his mission becomes near impossible. The scene is set for a classic story of pursuit, evasion and a battle for survival.
