Focusing on the Sears Merchandise mail-order warehouse in Chicago, this early example of Blumberg's personable documentary approach begins as an informative look at the mail-order distribution process, and ends as a candid observation of management/labor relations. A plant supervisor narrates and guides the tour along the conveyor belt system that connects the stages of the mail-order trajectory, which becomes Blumberg's "storyline." Employee satisfaction, job efficiency and labor standardizations are conveyed through brief interviews with the workers along the belt, culminating in a confrontational dialogue between a worker and her employer.
