Ludwig Bonhoeffer has been looking forward to this opportunity for all of his life. Ever since he attended a lecture by one Doctor Berwick, he's dreamed of becoming a neurosurgeon and assisting Berwick on his project: CORD. A computer system designed to perfectly interface with the human mind and help to wake comatose victims.

But when an accident leaves Ludwig at the mercy of CORD, he finds that not all is as it seems. Inside CORD is a labyrinth of imprisoned minds and haunted people. Only one has managed to retain her sanity - Mara. The rest have given free reign to their darkest tendencies, led chiefly by Lucy - a psychopath who believes himself the incarnation of Satan.

With Lucy out for his blood, can Ludwig unravel the mysteries of CORD and wake the sleepers up?
