Alfons, the easy-going and extremely charming boss of "Betten Keilinger", can always rely on the loyalty of his secretary, the single Hannah Zorn: Tireless, creative, selfless, she has been at his side for many years. When he falls in love with the young designer Jette, he asks Hannah to be his right-hand woman and look after his neglected wife. Hannah, herself no stranger to Alfons' charm, gets caught up in a grueling relationship vortex - and not just her. But because Hannah has always been a very determined person, in the end Alfons has to fear losing everything: especially Hannah!
