A serial killer is rampaging through the streets of the city known as the spiritual capital of Iran. His victims are poverty-stricken women who have become prostitutes. The tool of crime is the scarves that cover their heads, turning into nooses of death for unsuspecting girls. Rachimi, a fearless journalist, takes up this case. Risking her life, she goes into battle not only with the killer himself, nicknamed the Holy Spider, but also with the conservative society, which tends to justify the rampant killer who supposedly performs "spiritual purification". Zar Amir-Ebrahimi won the best actress award at this year's Cannes Film Festival for her impressive performance. A thriller that immerses you in the world of darkness, tension and religious vicissitudes is an unexpected turn in the filmography of director Ali Abbasi, whose previous film "Riba" was nominated for an Oscar.
