NP 8901 Royal Marine George Thomsen is enjoying a drink at a farewell party after spending a 12 month tour of duty on the Falklands. But celebrations on 'going home' are cut short as he is hauled from the party to learn that his duties in the South Atlantic are very far from over. He is ordered to pick 8 men and to embark on the HMS Endurance the next morning, for the most dangerous mission of his career. 800 miles to the south East, scrap merchant Davidoff accompanied by argentine troops masquerading as his employees, have raised the Argentine flag over the distant frozen island of South Georgia - British territory and the base of The British Antarctic Survey Team. Davidoff has held up one finger at The Empire and set the match to the touch paper that will escalate into all out war. Lightly armed and stranded by a departing HMS Endurance, the tiny besieged and outnumbered force make ready for a classic battle to protect the island and its scientists, against massive odds, from the air, land and sea.
