This story took place during World War II. A group of Italians living in London are raising funds to rebuild a Catholic cathedral that was bombed by the Nazis. To this end, they organized a concert, the proceeds of which would go toward the construction. The project was led by journalist Carlo Scala. He faced and overcame many difficulties in organizing the event, but he handled them with honor, and the performance by leading Italian singers took place. He was assisted in this by the incomparable Dora Scala.
