Lola (Anna Ammirati) is the teenage daughter of widow Zaira (Serena Grandi) living in a small Po Valley town (filming location is the ''comune'' of Pomponesco and Dosolo) in the 1950s. She is engaged to young Masetto (Max Parodi credited as Mario Parodi), who firmly believes in girls' virginity before marriage. They are soon to get married, but she is very much intrigued by sex, and further provoked by the antics of her libertine stepfather André (Patrick Mower), but Lola's approaches to Masetto for premarital sex jeopardise her relationship with him.
