Charles and Mary Brady arrive in a quiet Indiana town carrying a predatory secret: they are sleepwalkers, shape-shifting creatures who drain life force from virgins to survive. Charles targets Tanya Robertson, a warm and trusting high school girl drawn to his surface charm. The hunt runs through small-town routines, a cemetery date gone violently wrong, and a domestic tension between mother and son that carries unmistakable erotic charge. Cats are their weakness. Tanya is their meal ticket. Nothing about this town is safe.
