Following a botched operation in Afghanistan, Bowman is recruited into 'The Cell', a covert unit within the SAS working alongside the police - a unit so secretive most of the other guys in the Regiment don't even know it exists.

Their mission: to tackle international organised crime that threatens British interests. In a world where the Russian government is the real mob, it is the job of the Cell to take the fight to the enemy. But when a notorious British fixer to the Kremlin goes on the run, Bowman soon finds himself drawn into a deadly conspiracy, and a race against time to find his target - before the Russians get to him first.
