Angela, a 16-year-old student, and Gianni, her classmate, get to know each other and one day fall in love with each other. Convinced that the physical union must seal and not precede or further the sentimental one, the girl wants to be sure that the emotional bond is firm and deep before giving herself to her boyfriend.
