Where is Swiebertje? Even his best buddy Malle Pietje hasn't seen him in months. The Mayor sends out police officer Bromsnor to look for Swieb. But that's easier said than done...

Miss Saartje has a bad day. she burns a hole in her underskirt while ironing, it starts to rain while the laundry is hanging outside and the buns are burning. But Swiebertje wouldn't be Swiebertje if he didn't know a way to cheer up Saartje!

Swiebertje stays overnight at the castle, because he is busy with a job for the Baroness. All beds in the guesthouse are occupied and that is why Swiebertje becomes the sleeping mate of Jacobus, the Baroness' servant, for one night. Hope it turns out fine!

Saartje's birthday is tomorrow and our poor bum has no money to buy her a present. Swiebertje comes up with a plan to obtain a beautiful bunch of flowers: he picks up the geraniums from Bromsnor's garden. But whether that is such a good idea?

The Baroness' staff are fed up with the miserable life they lead. When the cook 'finds' the Baroness' cash box, they decide to run off with the money. What they have not counted on, however, is that the chest has another surprise in store!

It is raining heavily, but Swiebertje remains dry. He has the umbrella from Saartje to borrow. Constable Bromsnor thinks his own and confiscates the umbrella. But what will Saar say about that?

The baroness' jewels have been stolen and she is convinced that Swiebertje is the culprit. To prove his innocence, Constable Bromsnor and Swiebertje devise a ruse to unmask the true perpetrators.

Swiebertje is broke and cannot find a job anywhere. Then he runs into his old comrade Tommy Sanders, who has a job for him ... in Canada! To the great sadness of everyone, Swiebertje decides to leave, but not before a nice farewell party has been given !!
