The city council comes into contact with a cultural exchange project in the United States, which proposes to have an average family of either country live for a year in the other one.
At the reception, a young man named Geoffrey sees daughter Kees and immediately tries to hook up with her, claiming he instantly fell in love.
When the family gets back at the Plaza Hotel, the staff has found out about the mix-up and the Flodders are thrown out, forcing them to spend the night in Central Park.
A few days later the Flodders and the Rosenbaum couple have redecorated the night club, while at the same time Sjakie and his homeless friend are released from jail.
Not wanting his son to be involved with a white trash girl, the president decides to go the nightclub incognito, to talk daughter Kees out of the affair.
The water tank is launched into the air and flies over Manhattan (spotted by characters like the homeless person and the muggers) after which it hits the head of the Statue of Liberty.
In order to prevent a scandal, the American government makes an agreement with the Dutch embassy and has the Flodders released from jail, on the condition that they leave the country.
Simultaneously with the film release the movie was also adapted into a comic book written by Dick Maas and Wijo Koek and drawn by Marcel Bosma.
