The Roman neighborhood of Trastevere is looking for the girl to represent them in a beauty contest. The organizers decide that the professor is the judge, but the drawback is that the proposed beauty is his own daughter.

Penny is attracted to a slightly older boy Roy while Grandpa wants to date Stephanie, a lady young enough to be his daughter.

The countess has a problem: her son is in love with the professor's daughter. Both are poor and this marriage would be a financial failure. Love can overcome all and they decide they will wait.
