This film didn't quite make the splash that "Jaws" did two years earlier but remains a fine picture with tense moments and fine underwater photography. The stars, Nick Nolte and Jacqueline Bisset, a vacationing couple, find a different kind of treasure in a wreck off the Bermuda shore and soon have the island thugs around to pay them a visit. Seems as though a cache of morphine could be profitable in the drug market, which a Haitian dealer desires to exploit. The latter uses intimidation and voodoo to get his point across to the couple, who later get help from a seaman and treasure expert to keep the villains at bay. Bisset is nice to look at in her wet t-shirts and shorts but Robert Shaw and Lou Gossett supply the key moments of drama in the film more than do Nolte or Bisset. The picture does drift off course in spots but Shaw and Gossett stay on a collision course that results in an exciting undersea climax. The film never received its due as an adventure worthy of critical acclaim.
