One of the sillier 1950s fright night flicks, and directed with little imagination. An unlikable search party arrives at a small African plantation with hopes of retrieving a cargo of diamonds from the bowels of a ship that was sunk some 60 years earlier. The only problem is that the treasure's being guarded by a small band of sleepwalking-style zombies (the original sailors who went down with the ship when it sank) and they've done a fine job so far of killing every other search party that has intervened over the decades. The elderly wife of the zombified captain is still alive and wants the diamonds too, but only to destroy them so she may give rest to her husband's wandering soul.
That description is much more interesting than the way the movie actually pans out, but at least we've got the stunning Allison Hayes to gawk at as she plays the bitchy babe with the killer figure. There are some very weird underwater simulations when the divers are attacked by the dutiful zombies, who somehow are able to walk straight across the ocean floor without floating to the surface. ** out of ****
