When I found this movie some years back in the discount bin for 1,50 I decided to give it a go. I have to admit it's cool cover art lying amongst generically looking DVD covers really caught my eye. The movie itself turned out decent, it isn't anything special nor is it a complete failure like some people may have pointed out.
The story revolves around a nearly bankrupt Captain named Max Cash who lives on a fictional island called San Sebastian. His surname says it all! He comes up with all kinds of fascinating stories about the sea just to stay in business. He hooks up with a beautiful blonde who is interested in his services and wants to rent his boat to do some treasure diving. As the story progresses they encounter stormy weather, bad luck, some clues, a mysterious individual, rivalry an eventually start romancing.
The pro's include: a good story, some funny wisecracking dialogue and at least one realistically looking fight scene.
The con's include: The slow pace of the movie, even though it got released in 1989 it looks pretty early 80s (this may affect some viewers) and it's misleading horror genre.
To all adventurers out there! Watch and learn about treasures of the deep.
