A dybbuk, for those unfamiliar with the term, is actually a wandering evil spirit that has left a human body and is searching at length for a new host. The term and the concept originate in Kabala lore, and more specifically in a Chassidic folktale and a play by Szymon Anski. As an adaptation of Anski's play, this feature from the acclaimed Agnieszka Holland (Europa, Europa) begins with a minor tragedy - the paternal betrayal of a nuptial promise between a bride-to-be and a yeshiva student - and expands into something far more sweeping and sinister: the yeshiva student vows that he will harness the power of the spiritual realm via Jewish mysticism and inhabit the young woman's body at any cost.
