There is still swimming in Zandvoort aan Zee

On the beach at Zandvoort, a small group of people walk by, one of them wearing a bathrobe and slippers, the others thickly dressed; the man in the bathrobe strips off his clothes, runs, dressed in swimming trunks and a shirt, into the sea and swims around in it; the cameraman films him; after his bath he puts on his bathrobe again.
