John Carpenter's Tales of Science Fiction: HELL #2
HELL #2 (of 8)
Born in the Underneath ... trapped in the Overworld ... the calm, inhuman visitor known as KARTKAS is charged with helping a human team visit and explore his stomping grounds ... the regions beneath ... commonly known throughout history as HELL.
Their journey only starts in the Bermuda Triangle, aboard a ghost ship - a haunted tanker.
BENEATH THAT: A violent steam tunnel breaching the Atlantic Ocean floor.
