North Sea, 1982. A ruthless terrorist attack on the desperately vulnerable oil fields has left rigs destroyed or hijacked, the Prime Minister held to ransom and Great Britain facing economic collapse. The world's top security agencies were left stunned and helpless. Only one elite fighting force could meet the terrorist threat.
It was up to Tony Masters and the men of the Royal Marines Special Boat Squadron, the legendary SBS, to attempt the impossible. Their objective: to defeat the terrorists, rescue the Prime Minister and regain control of the oil fields – all while battling against the deadly North Sea.
