The badge of the Corpo de Bombeiros Municipais de Lisboa, with the motto “Sobre todas excelente e maiorial” (the best of all others) is shown in detail. At the corps headquarters, all the officers and chiefs of the corps pose for the camera as in a still anniversary photo. The action starts in a nameless street, when someone runs to warn a policeman of a fire in a building. They both run to a wall booth, the policeman opens it, takes the telephone and calls the fire brigade headquarters, where a permanency gives the alert. Sleeping in a dormitory, the firemen jump off their beds, dress their uniforms in no time, and descend to the garage via a sliding post (almost off camera). Two motorbikes with sidecar, two all purpose vehicles, an open truck with firemen, a water-tank vehicle, and a Magirus-Leiter truck leave headquarters and drive quickly to the house in fire - where different phases of a fire attack exercise are shown, from linking the hoses to water sources to saving people who jump from windows onto blankets held up by the firemen.
