Cloche gives him three days to recover them. Treece makes a deal with Cloche, so they can dive in peace making him believe he will get the ampoules for a million dollars, while his real plan is to have the chance to find the treasure. Treece concludes that a recent storm has exposed her cargo of morphine and unearthed a much older wreck containing Spanish treasure. The wreck of the Goliath is considered dangerous and is posted as off-limits to divers due to the danger of explosions. The ampoule contains medicinal morphine from the Goliath, a ship that sank during World War II with a cargo of munitions and medical supplies. The ampoule is noticed by the man who had rented diving equipment to Sanders and Berke, which in turn attracts the attention of Henri 'Cloche' Bondurant (Louis Gossett, Jr.), a local drug kingpin for whom the shop owner works, who unsuccessfully tries to buy the ampoule and then begins to terrorize the couple with Haitian black magic. Sanders and Berke seek the advice of lighthouse-keeper and treasure-hunter Romer Treece (Robert Shaw) on the origin of the medallion, who identifies the item as Spanish and takes an interest in the young couple. While scuba-diving near shipwrecks off Bermuda, vacationing couple David Sanders (Nick Nolte) and Gail Berke (Jacqueline Bisset) recover a number of artifacts, including an ampoule of amber-colored liquid and a medallion bearing the image of a woman and the letters "S.C.O.P.N." (meaning "Santa Clara, ora pro nobis" or "Saint Clara, pray for us") and a date, 1714.
