Octopus

Armageddon on the high seas! An elite nuclear submarine, on a deadly mission to deliver an international terrorist to American authorities, travels through a mysterious ocean portal known as "The Devil's Eye." Twenty-seven ships have disappeared in this area, fueling the legend of a killer mutant octopus. The terrorist escapes to a passing cruise ship, but no one is safe as the octopus unleashes its fury. Adrenaline-pounding fear surfaces in the grips of a monster few have ever seen. Even fewer will live to tell.
