In 1989 South Florida, four teenagers dare each other to touch the Witch's Wall - a notorious Palm Beach urban legend blamed for decades of tragedies. When Olivia presses her hand to the rusted grate, she's marked with a wound that refuses to heal, and soon she and her friends are plagued by nightmares of ghostly children and a witch with glowing red eyes.
As the infection spreads, the teens uncover the truth: Saniyah Duvall, a healer entombed alive in the wall a century earlier, cursed the island's children and now seeks to claim Olivia as her own. To break the curse, they must confront the legend head-on before the witch consumes them all.
