The son of her neighbour, Gerrit van Buren, has a crush on Sientje, but she craves more excitement.
She meets the artist Jan Meiren and is fascinated by his art and smooth manners, and decided to have him teach her to sing and dance, and to perform together.
Jan en Sien keep performing in Belze's café, but their relation doesn't improve, especially when Sientje gets pregnant.
Belze Marie and her husband have a smooth-running cabaret in Den Haag, and Jan Sien follow them there.
Jan is showing an interest in the blond dancer Angelique, and when these two start a relation, Sientje flees from the café.
