Two Zeeland girls in Zandvoort

Mijntje and Trijntje, two girls from Zealand, go to Zandvoort in the tram. On the tram they are seen by two young men who start flirting with them. Arriving at the beach, the girls decide to go swimming and they hire a bathing machine. They are so naïve that they put on their bathing costumes over their voluminous underwear. After playing in the water and ducking a little boy who has been splashing them, they come out and start frolicking on the sand. A policeman arrests them for disturbing the peace. The film ends as the repentant girls are led away to the police-station, where they are locked up. Twee Zeeuwse meisjes beleven dolle avonturen met twee jongemannen op het strand van Zandvoort.
