18-year-old Sebastian, played by the discovery Matthias Schoch, decides to go to Geneva as an au pair for a year. Yet you don't only learn French beyond the «rösti trench». His adventure, strewn with mishaps, becomes an invitation to life and love. Finally adult and free? You wish! His father sees him as a future boss of the family-owned printing firm and his mother only wants the best for him. Sebastian can't take it any more. On his eighteenth birthday he announces his departure to Geneva to work as an au pair in a family, looking after children and doing the household. To improve his French, of course. His father flips his lid, his mother is distraught. Only his sister Kathrin thinks her little brother is really cool.
