A German doctor named Carl comes to humorous terms with his new life, love, and work as a legal alien in London.
Carl graduates from American as well as German high schools and from German medical school. After his clinical studies, he becomes a GP in his own practice. For a time it seems that collecting certificates is his true meaning in life.
His new best friend, an agent who sells German doctors to companies in the UK, places him in a private company in the center of London. There Carl treats patients with strange diseases. Well, later he finds out that the patients actually have the same diseases. Only they call them differently. At least the patients aren't that much different.
Carl settles down some and makes friends inside the company. Who stay his friends even when he finds himself outside the company. Which fascinates him. And his new friends convey to him that he is loved and appreciated, especially a bright young lady named Alina from another foreign country, so he doesn't feel so alone.
