It May Be Love But It Doesn't Show

Salvo and Valentino own a sightseeing bus that takes tourists around Turin. Salvo is a bachelor always on the hunt for women, while Valentino is madly in love with Gisella, whom he showers with little hearts and other sentimental trinkets. So much so that Gisella has grown tired of it... She asks Salvo to tell Valentino that she wants to break up. Salvo himself doesn't realize that the beautiful Sonia, who's dragging an American fiance along behind her, actually has eyes only for him.
