The Deep

David Sanders and Gail Berke are scuba-diving near shipwrecks off Bermuda. They recover an ampoule containing morphine from the Goliath, a ship that sank during World War II with a cargo of munitions and medical supplies. A local drug kingpin terrorizes the couple with black magic and terrorizes them. They find out the true provenance of Spanish treasure from the wreck of a Spanish shipwreck. They make several dives to the wrecks, recovering thousands of morphine ampoules from Goliath and several additional artifacts.
