Six fire engines are driven by UK firefighters across Europe to the town of Banja Luka in Bosnia Herzegovina. Howard Leader watches and records while the British firefighters put a mixed ethnic group of Serbs, Croats and Bosnians through a crash course. In just five days they are welded into firefighting teams with exercises ranging from first aid to rescue, after which they return to their own units in Bosnia Herzegovina, the lucky ones with one Of the Six British fire engines.
