On 20 January 1942 senior representatives of the Nazi regime meet in the Wannsee villa. They discuss the murder of millions of Jewish men, women and children. The killing has already begun at this point. These men plan the next steps to be taken.

The exhibition places the meeting into the context of the anti-Jewish policy of the Nazi regime. It shows that many institutions and individuals are involved in the mass murder. It also asks how the so-called Wannsee Conference and its participants are perceived after the war.
