Years later, their grizzly brand of retribution has followed them into their new lives away from the Great Orme.

But the dead urge Zac to confess their crimes and the Great Orme wills it. And so, he summons the six back to the Great Orme, to persuade them to give up everything.

When one of the six starts killing again, they won't stop until Zac backs down. Zac must find out who the killer is and stop them if they are all to escape from the guilt and ghosts of their past.
