"Festival of Hearts" is the name of the new pop music show by popular DJ Camillo. He came up with the idea by chance. Marcel, a young bank employee, almost hit a charming young girl with his car. Angry, she lent him her jack, but then disappeared forever. He cannot forget her and tries to find her again through the show "Schlagerfreunde" (Schlager Friends). And that becomes the idea for Camillo's new show: to bring couples who have lost each other back together through a melody. For Marcel, it happens faster than expected, because his great love is none other than Camillo's secretary, who can follow his cries for help from the control room.
