Swimming near a Mexican village that has been terrorized by a sea monster, Julie Blaie (Anne Kimball), and American artist, is terrified when an object rises to the surface. It turns out to be a one-man submarine piloted by biologist Steve Dunning ('Stuart Wade' (qb)). Later an abalone diver vanishes and Julie faints after seeing the monster's eye rise from the sea. Pablo (Wyott Ordung) and Tula (Inez Palange) plot to offer Julie as a sacrifice to their gods. Pablo deliberately attracts a shark while Juilie is skin-diving, but she escapes, and her line snags an object that Steve and Dr. Baldwin (Dick Pinner) establish as part of a huge sea monster.

Fun Adventure Tale
24 September 2002 | by (Newfoundland, Canada) – See all my reviews

Sure this movie is cheaply done and features very few special effects but nonetheless there's a surprising amount of high adventure in this tale. Even better and more unique for the period--our hero is actually an heroine! The music(apparently done by Andre Brummel)is actually extremely well-done and adds considerably to building up the tension. Overall it's as I said above--it's a fun adventure story and one which wisely doesn't go on for too long.
