Every intelligence agency in the world supports its own Special Operations unit comprised of teams of highly trained operatives. Their job is to undertake politically sensitive, dirty and often dangerous assignments. There is no glamour here, just shadowy anonymity and the acceptance that death may come quickly. The Special Operations Unit of the British SIS is nicknamed, "the Sandbaggers." Neil Burnside (Roy Marsden), ex-Sandbagger, dedicated professional and now Director of Operations for SIS, shrewdly leads the unit with decisive ruthlessness. SIS and the Sandbaggers are his life. Now digitally re-mastered, this highly acclaimed series dramatically sweeps viewers along Westminster's often Machiavellian corridors of power where conflicting political needs can result in questionable decisions, then out into the murky world of espionage where those decisions meet stark reality.
