In 2001, a Tehran journalist is investigating a series of femicides in the dodgiest neighbourhoods of the holy city of Mashhad. These crimes are thought to be the work of a single individual who claims to be cleansing the city of its sins by murdering prostitutes at night. Holy Spider works as a fascinating mirror of Iranian society. It is a film at the crossroads of genres, which displays strong originality, and tackles the condition of women in Iran. A must-see!
