A film about winter railroading in the Canadian Rockies and the men who keep the lines clear. The stretch between Revelstoke and Field, British Columbia, is a snow-choked threat to communications. The film shows the work of section hands, maintenance men, train crews and telegraph operators.

This film shows the scientific study of fires set to buildings in Aultsville, Ontario, a town evacuated for flooding by the St. Lawrence Seaway. Scientists at Canada's National Research Council devised instruments for recording the progress of a fire in all its stages, to help the country's fire fighters lessen fire's tragic toll.
