A large number of workers, mostly young women, leave by the front door of their work place at lunch time. The building has an impressive colonnaded facade, and is located at 181, Santa Catarine St., Porto - one of the city's main streets. A passengers' horse cart crosses from right to left of the screen, and a few seconds after an ox cart carrying merchandise crosses in the opposite direction. All the while, workers keep leaving the factory, giving a sense of a large work force.
