When a bomb explodes in a British RAF base in Germany, MI5 terrorist specialist Bull (Bill Paterson) is called in to investigate. However, the further he begins to dig into the secrets behind the terrorism, the more he finds himself immersed in dodgy goings-on in the corridors of power of NATO itself.
