When his ship docks at Copenhagen, shortly before Christmas, he signs off with all his hire on the pocket. He seeks accommodations in sailor home Bertel, located on the nice side of Nyhavn. Here he can stay and eat for very little money. He delivers his kitbag to the concierge Henrik (Mogens Hermansen) before he was lured by accordion music and the laughter that comes to him from the "naughty" side of Nyhavn. In the Cafe "The black sails", he accidently joins Inger (Lisbeth Movin) at the same table, whose profession is not in the phone book, although it is the world's oldest. Inger is in the company of an unemployed stoker Vladimir W. Olsen (Poul Reichhardt) that is full of scams, and has a good mood.
