The film follows the life of a couple of singers from Münster who became known for covering the most prominent voices of distinct eras of Schlager music. While Markus got recognition through youtube tributes to Udo Jürgens (known for introducing French Chanson in 1970’s Schlager) Steffi often performs the repertoire of Helene Fischer, a contemporary Schlager icon who opened the genre to a Global Pop standard.
