Stratton

After a failed mission to destroy an Iranian bioweapon, British Special Boat Service operator Sergeant John Stratton, working for the Intelligence Detachment in Northern Ireland, tracks down the terrorist cell who used the mission as cover to steal the weapon for their own purposes. Due to the failed mission, Stratton suspects a mole. His boss Sumner recognizes the terrorist leader as Grigory Barovsky, a Russian spy, presumed dead for nearly twenty years. They learn a bomb maker has developed a drone system to disperse the bioweapon, which is more lethal at high altitudes, and track the terrorists to Rome.
