In the early days of "sex ed", producers of feminine hygiene products were quick to produce educational films targeting girls that would prominently feature their products. In this one, a mom tells her young daughter all about the wonders of the Modess line of products, while trying to help her cope with the changes her body is undergoing. Later, her her teacher calls on her to help explain menstruation to the other girls in the class. All the boys that were excluded from these sessions may now finally discover what happened when the girls all went off to that "special class" together.
