the summer they were eleven, they killed a man and buried his body in a cave. since then, every year, one summer night has marked a ritual: a ritual never to forget, and never to betray. five years have passed. their sixteenth summer. the body, now a skeleton. unraveled lies. a faceless blackmailer. the phone rings and a life is torn apart. the bones, like their crime: never rotting, never fading away. now, a living hell begins.
