Juan Cabrillo and the crew of the covert combat ship Oregon have
barely escaped a mission on the Congo River when they intercept a
mayday from a defenceless boat under fire off the African coast.
Cabrillo takes action, saving the beautiful Sloane Macintyre,
who's looking for a long-submerged ship that may hold a fortune
in diamonds. But what surprises Cabrillo is her story about a crazy
fisherman who claims to have been attacked on the open sea by giant
metal snakes in the same area. What begins as a snake hunt leads
Cabrillo on to the trail of a far more lethal quarry - a deranged
militant and his followers who plan to unleash the devastating
power of nature itself against all who oppose them.
