John Carpenter's Tales of Science Fiction: Hell

Is it one of those assemble-the-team deals? YOU BET! The scientist. The murderer. The mercs. The witch. And the half-human visitor from the Underneath. The mission: Recover the most amazing mineral power source ever discovered. The target: Miles beneath the Earth's crust, teeming with monster denizens we haven't seen in centuries. It's a one-way trip straight to HELL.
