Director Mauro Bolognini and Goffredo Parise adapted a skillful Alberto Moravia story into this rather pedestrian drama. An eligible widow (Ingrid Thulin) vacations in Venice with her young son. When Thulin begins a tentative romance with friendly John Saxon, her resentful son runs away from home and gets into trouble, falling in with a gang of hooligans. The rest of the film is bland and predictable, as the harsh realities of street life teach the youngster some valuable lessons, most of which are hammered home with redundant narration. Plot mechanics aside, however, Aldo Tonti's rich cinematography still makes the film worthwhile for those who swoon at the sight of the Lido.
