Budapest is a tragedy of the Jewish genocide set in war-torn Hungary in 1944-45. As the German Nazi bureaucrat Adolf Eichmann arrives to sweep up Europe's remaining 430,000 Jews for the deaIth camp at Auschwitz, a battle-decorated German Army major meets an ethnic-German but Hungarian industrialist who is married to a much-younger wife who is half-Jewish. They become close friends as the major and his company battle to keep the Soviet army out of Hungary. The industrialist and his wife have a secret that they are even unaware of - their 23-year-old son is of uncertain parentage, and as a member of the incoming Hungarian-fascist Arrow Cross government he is busily collecting Jewish names and addresses for Adolf Eichmann. On a disastrous whim, he checks the archives on his own family and finds his father was previously married to the countess, who died in childbirth on the very day he was born. He also finds his "mother" is part-Jewish. Who is his mother? What if HE is part-Jewish? Is his mother his mother? How can he irradicate her from his family history?
