El baile de los vampiros

Professor Ambronsius (Jack MacGowran), an eccentric old academic specializing in the study of bats, and his bumbling but well-meaning assistant, Alfred (played by Polanski himself), travel to a small village in snowbound Transylvania (actually, filming took place in the Italian Alps) that has been plagued by a clan of local vampires. After innkeeper Shagal's comely daughter, Sarah (Sharon Tate), is abducted by Count Von Krolock (Ferdy Mayne), Ambronsius and Alfred venture out to the count's castle to rid the area of its bloodsucking parasites once and for all--a dangerous undertaking indeed, especially since it soon becomes apparent that traditional weapons against the undead are not quite as effective as folklore would have one believe and that attractive young maidens are not the only ones in danger of becoming victims of a vampire' uninvited advances.
