Meeting in Poland during the Second World War, Leo Zimm and Max Eisenhardt were friends. They were separated from one another by the Nazis, who were sorting the prisoners into various concentration and death camps. Eisenhardt was eventually interned at Auschwitz, while Zimm never made it to the camp he was intended for. Instead, he encountered a vampire, who transformed Zimm into a vampire as well.
