Kærlighedens melodi.

Nina and Frederik were the big names in international showbiz in the 1950s with their rousing calypso rhythms. That's why "Kærlighedens Melodi" (The Melody of Love) was bound to be a hit when the young, beautiful couple teamed up with the legendary, wonderful "Satchmo," Louis Armstrong, from the world of jazz. Musical interests vary widely in the affluent neighborhood of Hellerup. At the Schmidt wine merchant's, son Peter has only one interest: jazz. At the Supreme Court lawyer's house next door, Mozart is on the program. But his daughters like both jazz and Peter! Even though their fathers are suing each other, the two young people still find each other. And Louis helps when he plays "The Formula for Love."
