Set in Scotland, this film tells, among other road transport matters, the story of a team of four British Road Services drivers who lived and worked together for two years, loading and transporting 20,000 tons of cement in 7 1/2 ton loads up craggy mountain roads from the little railway station at Killin to the new Giorra Dam. A concentrated effort relying on hard work, co-operation and the support of British Road Services nationwide organisation.
