A young diver-for-hire (Dean Cochran) sees his father, as well as a several other divers, get eaten alive by a school of Great White sharks as the posse tries to retrieve diamonds from an ancient sunken ship. A decade later, he finds himself in the same predicament -- and again later -- but this time with his wife (Brandi Sherwood) and young son in danger, and not just from sharks, but from smugglers, as well. ~ Buzz McClain, All Movie Guide
