The Fifth Wheel to a Coach (1958)

Although the emancipated editor of a women's magazine preaches that grandparents in particular should not be abused by their adult children, she accepts without scruples the fact that her mother, still a sprightly pensioner, works in her household as a jack-of-all-trades, without receiving not only any pay but also no recognition. However, the grandmother learns from an article written by her daughter - and rebels.
