A young woman and her one-year-old daughter arriving from Monza walk towards Milan massive Central train station, in Piazza Duca D'Aosta. It is 10 November 1939, and we are in the heart of the metropolis: on a building in the square stands a large sign for Motta, the producer of panettone, a symbol of Milan, celebrating twenty years in business. On the façade there are also other advertising signs (of the record company La voce del Padrone and Radio Marconi). A few shots further on, we glimpse in the walls of a skyscraper the posters of films showing at the cinema, two titles of popular entertainment, the transposition of the play 'Il fornaretto di Venezia' and the musical comedy 'La mia canzone al vento'. The city offers many distractions for Alba, wife of filmmaker Franco Valtorta, and little Mirella, who is seeing it perhaps for the first time. So Franco takes the opportunity to improvise a little film trick on 9.5 mm film. The woman and the little girl smile at the camera in front of a departing tram: the shot, filmed in 'reverse', shows the tram approaching the two almost running them over. The pedestrians walking in the background in reverse reveal this little trick. No fear in shooting this scene, perhaps a few shivers for Mirella when she watches it older.
