Five friends made a mistake that changed their lives forever. What started as a reckless joke - burning down a church - ended in tragedy, leaving innocent people dead and guilt that would never fade.
Five years later, the past comes back with a vengeance. Someone knows what they did... and now they're being hunted. One by one, in the shadows, a figure wearing a terrifying nun mask is picking them off. No one is safe. No secret stays buried forever. As the body count rises, trust shatters, friendships crumble, and the five friends realize that sometimes, the sins of the past have deadly consequences.
Will Isabella survive? Can they escape the shadow of their guilt - or will the killer make them pay for the sins they thought they'd buried?
