After more than 40 years, the fractious family branches from East and West meet again for the first time, and the old feud threatens to break out again. The fact that some opposition artists from the neighboring "Möwe" have mixed up among the guests does not make the situation easier for the West Berlin event manager Karin Wiesel.
