Gitarren klingen leise durch die Nacht (1960)

Austrian singer-writer Fred Wiskott is a hit in Viennese showbiz, and enjoyed countless affairs. Just when he's finally ready to commit to one girl, chosen show dancer Ninon Lorraine commits a suicide attempt. Fred goes on holiday to the Sicilian fishery port of Taormina with his friend, painter Paulchen 'Paolo' Sperling. Fred immediately takes to local rascal Roberto, who cares nothing for girls, except his big sister Marina. But she considers Fred her way out into the big world. She manages to seduce him, which messes up her vocal trio with Salvatore and local admirer Jacopo, while Paul convinced Nannon to visit and get him back.
