[3] While she enjoys her promiscuity and carefree, urban single lifestyle, Christa seeks marriage with a man who will accept both her and her son Rolf, who lives with her parents.
As Christa forms temporary relationships with an Italian businessman (who does not want to be a stepfather), an American artist (who wants an open marriage), and a French conductor (who tells her that he is too dedicated to music to give her what she wants), a private detective follows her.
Torben, wealthy and reckless heir to a family fortune and Rolf's father, tried to force Christa to abort their son.
He insists to her that she will return to him and secretly builds a library of dossiers on her lovers, while his business empire collapses from overaggressive expansion.
Torben threatens to use the dossiers and his greater financial resources to gain custody of Rolf, forcing her to end the engagement.
