Demonoid plot
"Up from the depths of hell comes the ultimate horror!"
In a silver mine, Jennifer and Mark Baines discover an ancient devil's temple that contains a silver briefcase in the shape of a hand.

Mark is overpowered by the hand and just as he threatens to be killed, the hand falls to dust again. Mark has changed, however; the Demonoid has taken possession of his body...
