While working in the body farm of her high school forensics class, Toni Donovan and her students hear sirens–and soon learn that Jake Crawford, owner of the local supermarket, has been killed. When a distraught school employee’s husband is arrested as a murder suspect and the friend asks for help in clearing him, Toni is drawn into the case.
Soon after visiting the crime scene, a series of personal attacks against Toni seem to indicate that the killer believes she knows his/her identity and means to stop her from revealing what she knows. Wading through a maze of suspects becomes a matter of survival for Toni.
