This film essentially begins with a small group of five treasure hunters getting together to search for a sunken Spanish galleon off the coast of Jamaica. To find the galleon they first have to locate a nearby cave that the Spanish may have used to deposit some of their gold coins and once that's found they can then use current technology to help them detect the sunken ship. What they don't know is that a couple of other treasure hunters are carefully monitoring their progress and they have no scruples when it comes to acquiring the gold all to themselves. Now rather than reveal any more I will just say that this film had all of the ingredients necessary to be a successful picture with a decent cast, an interesting plot and beautiful scenery to work with. Unfortunately, the slow pacing, basic script and the semi-documentary manner used negated all of the good points. So essentially, the gorgeous island scenery and the beauty of Cheryl Ladd (as "Zappy") were essentially wasted. In short, this was a rather dull film and I have rated it accordingly. Below average.
