Sailors in the course of a dangerous mission are confronted with a new kind of terror in this monstrous thriller. A terrorist wanted in several nations is captured by authorities and sent to America to stand trial. The criminal is being transported aboard a heavily guarded submarine, in hopes of foiling any escape attempts, but the sub is forced to pass through "the Devil's Eye," a region at sea where a number of ships have been lost. The submarine's crew soon learns the secret of "the Devil's Eye" when the ship is attacked by a giant, prehistoric octopus. In the confusion, the terrorist escapes to a passenger ship, and the crew must find the fugitive as they fend of the vicious sea creature. Octopus stars Jay Harrington, David Beecroft, and Carolyn Lowery. ~ Mark Deming, All Movie Guide
