A university student falls in love with a seamstress. But one day he meets a beautiful woman and things become complicated.
The movie is about a student in Turin during the 1920s (moved up from the earlier versions) and his love for a a seamstress. The student, Mario, is played by Walter Slezak; the girl Dorina by Carmen Boni. The femme fatale Elena (Elena Sangro) threatens the relationship. When school days end, seen here as a kind of transitory idyll, it is "farewell to youth" as the title states, and a melancholy goodbye to youthful romances as well to allow new lives to take form.
Two young men move to the city in order to study. One of them gets entangled in a love triangle.
