Synopsis: Miles offshore, the skeleton crew aboard Weyland's Drilling's "Charlie" Rig is preparing to ride out an oncoming storm. But 4,000 feet below, their drills have mistakenly unleashed a different kind of terror: its strength is inhuman. It slaughters without mercy. And it is hunting the stranded team one by one. Now, deep within the labyrinth of oil platform passageways, a group of tough-as-nails drillers must find a way to destroy a monster that lives to kill . . . or die trying.
