The CIA accidentally blew up a civilian vehicle while trying to capture the terrorist. Harm and Mac were officially sent to investigate the incident which involved "Gunny", but unofficially were there to find information on the terrorist. While in the mountains, Mac crashed into a minefield and Harm went flying. He stepped on a mine and Mac saved him. They started walking and stopped to set up camp for the night (they were snuggling to "keep warm" yeah right) and managed to find themselves right in the line of a US bombing run on suspected terrorist locations. The terrorist was not killed but Gunny's love interest was and the terrorist is still on the run planning a nuclear attack.
