In the movie Holy Spider, the journalist, named Sara, goes undercover to delve into the world of sex work and try to uncover the identity of the Spider Killer. She meets several sex workers who share their stories and struggles with her, and she begins to see the humanity and dignity in their work.
As she investigates further, Sara begins to uncover a web of corruption and misogyny within the city's religious hierarchy, who turn a blind eye to the murders in the name of maintaining societal purity.
Sara also forms a romantic relationship with a fellow journalist named Ali, who helps her in her investigation and provides emotional support as she confronts the brutal reality of the murders.
As the body count rises, Sara and Ali get closer to identifying the Spider Killer. But when they finally do, they realize that the culprit is not an outsider seeking to cleanse the streets of sin, but rather someone from within the religious establishment who is using the murders to further their own agenda.
The movie Holy Spider is a bleak but insightful look into the intersection of religion, sex work, and violence against women in modern-day Iran. It also highlights the bravery and resilience of those who stand up against oppression and fight for justice.
