"On the 24th April 1993, the IRA detonated a massive bomb in Bishopsgate, in the heart of London's financial district. The bombing nearly brought the British Government to its knees. It was clear they couldn’t afford a second attack. The Prime Minister wanted the IRA cell responsible located. His orders were simple - find them and eliminate them. They turned to the SAS.
One man stood out. Bruce Cole. His job? To infiltrate the IRA Active Service Unit in London. The problem? He won’t be armed or have back-up from any of the security services. He is on his own."
