This promotional film, presented by the United Gas Pipeline Company and the Southern Natural Gas Company, describes the Sea Robin pipeline, a submarine natural gas pipeline system that transports natural gas from the Gulf of Mexico to the Louisiana coast. Narrated by award-winning theater, radio, and TV actor Van Heflin, the film begins by presenting the pipeline’s attributes. Heflin then delves into the lifestyles and job descriptions of the workmen responsible for the pipeline’s success. He provides impressive statistics about the pipeline’s magnitude, but emphasizes the workers behind the project.
