Ein Existenzgründerseminar schwänzt Saskia Vester alias Henni Höffner gerne, wenn ein reizvolles Angebot reinkommt, das die Premium-Nanny nicht ablehnen kann. In "Mission Italien" bricht die sympathische Weltenbummlerin zu einer Familie nach Apulien auf, die angeblich nur ein wenig Entlastung für die Zeit der Olivenernte braucht. Kaum angekommen muss Henni aber feststellen, dass eine sehr fordernde Aufgabe auf sie wartet! Clelia Sarto und Janek Rieke stehen als Ehepaar, das den Boden unter den Füßen zu verlieren droht
Henni gets off the Munich-Bari suburban bus enthusiastically in sunny Apulia. Her new assignment leads the globetrotter nanny to a German emigrant family with two teenage children. Rosa Westphal, who runs a picturesque olive farm with her husband Benno, relies heavily on the teacher with the impressive references. It seems strange to Henni that the self-confident A student Luisa and the musically gifted but sensitive Julian need supervision at all - especially since the family's finances are obviously bad. In addition, Henni is amazed at a secret visit to the doctor by her client, which she happened to observe. Henni finds the husband's closeness to the attractive Vittoria, who is busy on the farm, suspicious. The violent quarrels between the couple also suggest little good. Henni wants to know what's going on with Rosa. But she doesn't let anyone get close to her. When Henni finds out the real reason, she realizes the extent of the worries.
La tata globetrotter Henni arriva a Bari con un bus partito da Monaco per andare a occuparsi di una famiglia tedesca con due figli adolescenti che vive in una pittoresca tenuta di olivi nella campagna pugliese. Sembra tutto sereno e Henni si domanda perché abbiano bisogno di lei, ma lentamente si scoprono gli altarini.
