It is one thing to open a beauty salon (which Edwige and her young lover Gaston have just done) but it is another to keep it on its feet.To best promote their speciality, fountain-of-youth treatments, Edwige decides to apply to the letter the old slogan "It pays to advertise" by posing as... Gaston's mother, a sixty-year-old woman, miraculously grown younger.
