Into the Blue (2005)

Down on his luck and perpetually impecunious, the experienced deep-sea diver, Jared, and his theme-park guide girlfriend, Sam, lead an idyllic and simple life in the sun-drenched Bahamas. Dreaming of striking gold, the couple along with Jared's solicitor friend, Bryce, and his new lover, Amanda, set sails for the vast ocean on a rickety boat, to claim ownership of a sunken pirate treasure of inestimable value lying next to a wrecked fuselage crammed with watertight cocaine bricks. Before long, the temptation to get their hands on easy money will lead to a dangerous head-on collision with the murderous local drug lords, as the team gets sucked deeper and deeper into an unexpected adventure amid the blue and shark-infested Bahamian waters. But, will the sea give away its riches so easily?
