Naples under the kiss of fire (1937)

Mario Esposito, who sings in a Neapolitan restaurant, is in love with Assunta, the niece of Teresa, the owner of the place. He shares his apartment with Michel, his best friend. This one has fallen under the spell of Lolita, a gorgeous adventuress he met at the cathedral where he officiates as the organist. But things go awry as, while Michel intercedes with Aunt Teresa for Assunta's hand in his favor, Mario in turn falls in love with Lolita. On the very day of his wedding with Assunta, Mario runs away with Lolita, thus betraying both his love and his friend. But it does not take long before the young singer realizes the big mistake he has made.
