Nine Miles Down

Thomas 'Jack' Jackman, a security operative for an oil company, is sent to investigate the loss of contact with a team at a drilling station in the Sahara desert, where they were drilling deep down in to the Earth's crust. The place is deserted but then he encounters Jennie Christianson, who claims to be the only survivor after the rest of the team went mad. After drilling to a depth of nine miles they all began to believe that they had drilled into hell and released something evil. The longer he stays there the more tragic events from his past come to haunt Jack, and he comes to believe that Jennie is an imposter and may be the evil that has been released.
