The sympathetic music teacher Clarissa Springer leads a thoroughly average, but contented life in Freiburg. She lives with her father Walter, whom she has cared for since her mother's death. Although her boyfriend Marco urges her to finally move in with him, Clarissa does not have the heart to let her father "down", at least not so shortly before his 70th birthday. A special, rare guest arrives on Walter's day of honor: Ina, Clarissa's younger sister. Ina, beautiful and internationally successful as a model, turned her back on her homeland years ago and lives in Paris.
