La scuola dei timidi / 1941

Alberto, who has a beautiful voice but is afraid to sing in public, and the shy Anna, daughter of a very rich shoe manufacturer, take "lessons of courage" in a school for the shy and end up falling in love. Their shyness doesn't seem to heal but due to a misunderstanding Alberto becomes terribly jealous, deciding to face the girl first and then the public who will give him an enthusiastic success.
