Elvira - The Sperm Bank Murderess of Gerolstein Castle(1994)

This time, The Sperm Bank Murderess of Gerolstein Castle takes the audience neither to Egypt nor to Babelsburg, but straight to the beautiful Eifel region, where bloodthirsty vampires live and men under pressure are helped quickly and unbureaucratically. Mother Elvira has a moronic, gay son who is finally to be fixed up. The victim: Petra Porn. In a cloak-and-dagger operation, mother and son set off for Bitburg, but end up in a cemetery where Count Otto von Gerolstein and his butler are up to mischief. The horny count gives Elvira a good vampire bite - and the dream of a part-time job in the blood bank is over. The lady is transferred to the sperm bank, where a master butcher falls in love with her.
