Henriette Höffner is finally fed up. She has now worked for around 40 years, but life is still a struggle - especially for economic survival. The encounter with the personable career advisor Mr. Loibinger gives Henriette an idea: Although she has neither training nor reserves, she has a lot of spontaneity, energy and life experience. In addition, it is as patent as it is unconventional and headstrong - it would be laughable if all these qualities were not put together in some way. Her grandson Toby helps her to set up a website that is not quite "straightforward", and Henriette actually got her first job in record time - as an exclusive international childcare worker. Her first trip takes her to the dream island of Mauritius, where she is supposed to help the newly widowed hotel manager Dieter Waldner, who is hopelessly overwhelmed in human questions, in childcare. Not an easy undertaking, because Henriette may have a talent for improvisation, but she lacks any routine when dealing with kids. Despite everything, Waldner's daughters Stella and Marie soon take Henni into their hearts, but dad himself turns out to be a much tougher nut. On top of that, he is about to run straight into his misfortune - thanks to the smart Munich "businesswoman" Veronika Fuchs, who wraps the hotel manager around her little finger. Veronika has a perfidious, ingenious and apparently watertight plan - in which, however, she did not count on the Henriette factor.
