A group of anthropology students discover that studying the past can be deadly in a slick, smart whodunnit horror. When they begin finding human bones and personal property scattered around their campus, it becomes clear that a gruesomely masked maniac is brutally targeting them, and late-night study sessions turn into a frantic race to solve the attacker’s identity before they all end up as a textbook homicide case. It’s left to Sheriff Bracco, Laurie, the County Coroner and their teacher, Kelly, to help find out who the real bone-crunching assassin is before another innocent becomes the next victim.
