The film describes the first working day of a twelve-year-old girl, shortly after the turn of the century. After a miserable childhood in a proletarian family, where she was mother to five toddlers, the sensitive girl follows in the footsteps of her parents and seventeen-year-old sister and sets off for the brickworks. The girl bravely defends herself at work, enduring the boys' bullying without tears, but when the day comes to an end, the foreman tells her that she must go to Krevelt, the boss, to be registered.
