Charming bon vivant Rudolf is convinced that infidelity is the
basis for a happy marriage, since, after all, a woman does not
want to be bored with her partner. Therefore, it is better to keep
her fighting for him. Rudolf, now in his Sixties, has successfully
applied his wild theory in everyday practice. Obviously, he does
not understand the naivety of his son-in-law Andrew, who tries to
be a dutiful husband. He decides to try to help him; after all,
he is the husband of his only daughter.
