Bill Manning, a saivage man, is hired by the lovely Wayne Shannon Macauley to run her- by boat- along with her husband- out of the country to Yucatan- by way of Scorpion Reef where a fallen plane hides a considerable cache. In the getaway, Macauley is killed, and Wayne and Manning are the easy victims of some ugly pursuants. They head into rough waters, but when they reach the Reef alone, it is Wayne who realizes the past is a yoke they cannot escape... The sea- a woman- and a buried treasure- all have their lethal lure. Concentrated.
