If your name is Kaj Jensen and you live on Frederiksborggade, there is a certain likelihood that you will be confused with Kaj Jensen on Fredriksberggade. But when botanist John Søgård from Mariendalsvej is mistaken for whaler John Søgård from the South Pole, who is home on vacation, it's not so smart. And disaster strikes! But in this case, it suddenly turns into a stroke of luck...
