Christoph (Mark Keller), Katharina (Maria Ketikidou), Kai (Volker Lippmann) and Beatrice (Caroline Schröder) work as animators in the holiday club Marengo on changing holiday destinations. Again and again they are moved to new places or move on freely. Everyone is young and good-looking and at the beginning has constant affairs with changing partners. Beatrice used to be with Christoph. After a while he discovered his love for Katharina, the two became a couple, and Baby Jonathan (Marcel Zeiger; later: Kevin Schirmuly) was born. Shortly afterwards they get married. In addition to his work as an animator, Christoph is drawn to the stage as a musician. He joins the women's band Ladycats as a singer and gives concerts with them again and again.
