Former SAS sergeant Andy McNab co-scripts this drama, based on his own experiences in the Gulf War. In January 1991, an eight-man SAS team infiltrate the Iraqi lines, with the purpose of taking out the scud missiles aimed by Saddam Hussein at Tel Aviv. In charge is Sergeant McNab (Sean Bean), who has to think fast when his squad are surrounded by two divisions of Iraqi troops, with no radio contact and sub-zero temperatures freezing their fuel supplies.
