A low-class antisocial family ends up in a rich upper-class neighborhood and causes all sorts of trouble.
The mayor of Sunny Dale see a chance to get rid of the Flodder family: They send the asocial bunch for an international exchange to New York. There they get confused with a Russian delegation of medical doctors while the street worker Werner who accompanies them becomes imprisoned.
Back from their trip abroad, the family must meet the people of the neighborhood while preparing for the 25th anniversary of Zonnedael. Ma falls in love with a bum that is not exactly what he seems to be.
