Ferienfieber.

Marcel Huber, an amiable family man without much assertiveness, accidentally takes his wife Jasmin and children Nicole and Sämi on vacation to wicked Amsterdam instead of sunny Rome. To make matters worse, their hotel turns out to be a lousy flophouse. The house is in trouble and they are in danger of having to cancel their vacation. In his futile search for a new place to stay, Marcel meets the self-confident Dutchman Jaap. He finds him a good hotel in no time at all. Marcel is very impressed by Jaap, who seems to master life in every situation. Marcel wants to be like him. Jaap soon gives the Swiss family man the opportunity to become an investor in a new nightclub project.
