Felix is ​​a stubborn and ambitious young man: he collects PhDs like other postage stamps. Now the Studiosus, who lives in Munich-Schwabing, wants to do his third doctorate, this time in law. But spring and the corresponding feelings towards beautiful femininity interfere with him. One day he meets the pretty Australian art student Jery. At first the two cannot stand each other, but then the girl falls in love with the new PhD student. The cute girl from Down Under tries to win the heart of the energetic young man with love advice that she has taken from a guide. Word of this soon spread in the trendy student world in Schwabing, and since then Felix became a popular crush among young women. To live up to his-undeserved-reputation as Casanova, he is no longer allowed to simply indulge in Jery, and Felix begins to play the role of an anti-bourgeois womanizer. Numerous entanglements ultimately lead to Felix not getting another Ph.D., but instead winning the hearts of his loved ones.
