The English-language title of this Mexican musical was The Third Word. Singer Pedro Infante stars as a pampered young man who is sheltered by his doting aunts. Deciding that their darling boy needs an education, the ladies hire pretty schoolteacher Marga Lopez. Upon discovering that her pupil is 28 years old, Marga is momentarily nonplused, but then settles into her duties. Inevitably, romance blossoms between Pedro and Marga, much to the aunts' dismay.
