[1] The young married couple Sigvard and Isabella Löfgren are constantly being sought by different companies where they are trading on the bill.

Sigvard is a traveling salesman and Isabella works as a secretary at a theatre agency seeking artists for a revue.

But when Gunnar signs up in with Isabella, she instead thinks he is seeking a place in the revue, he therefore gets a number and is called in to the theatre managers office.

A little surprised, he sings the song "Isabell" and then wants to receive his money for the coat that Isabella owes him.

When the theatre manager hears the story, he thinks it's fun and charming and wants to make a sketch of it all in the revue.
